Chuck Cunningham syndrome: Encyclopedia - Chuck Cunningham syndrome

Chuck Cunningham syndrome

Chuck Cunningham syndrome is a term that refers to when in which an important character in a television series is removed with little or no explanation.

The term comes from the character Chuck Cunningham in the American television series, Happy Days. Chuck, the oldest of the three children in the Cunningham family, initially appeared in the episode "Love and the Happy Days" (in the show Love, American Style), which served as the pilot for what became the Happy Days series. However, in Happy Days Chuck appeared as a superfluous character (usually on his way to basketball practice). Chuck was written out of the series at the beginning of the second season with the explanation that he was going to college. After the second season, he was never mentioned again; episodes referred to the Cunninghams as having two, rather than three, children.

On the Happy Days reunion special that aired February 3, 2005, a series of clips was introduced that pointed out that Chuck not only disappeared but also was played by two different actors over the course of the series (Gavan O'Herlihy and Randolph Roberts); both of them were then brought out, a surprise to Marion Ross and the rest of the cast.

A similarity to Chuck Cunningham syndrome can occur if episodes of a series are broadcast out of order, causing viewers to miss a farewell episode. Also, the syndrome often occurs when pilot episodes aired as part of a show's regular run include characters not in the regular series. An example is the character of Dr. Mark Piper, chief medical officer aboard the USS Enterprise in the pilot episode of Star Trek: The Original Series, "Where No Man Has Gone Before". This pilot was broadcast as the series' third episode, leaving viewers briefly confused as to what happened to Dr. Leonard McCoy, the ship's doctor in the previous two episodes and all episodes following.

This syndrome seems to be particularly prevalent in children's animated programming, particularly children's educational programming aimed at preschoolers / younger audiences. Oftentimes, characters will appear in the class that the main character attends from time-to-time, but be mysteriously absent in many or most episodes of the program. Or the character will appear, but not have any dialogue at all until later seasons of the program, in which sometimes they somehow simply become a part of the main character's group of friends without any explanation.

Chuck Cunningham syndrome - Examples of Chuck Cunningham syndrome

• 227: Rose's daughter Tiffany (Kia Goodwin) disappears halfway through the series' third season, never to be mentioned again.

• 24: Two-thirds of the way through the 2005 (fourth) season, the character of Behrooz Araz, son of terrorist Navi Araz, is handed off to central villain Habib Marwan's cell in return for the captive Jack Bauer. He is not referenced for the remainder of the season, despite the continued presence of the terror cell to which he was passed. In subsequent interviews conducted after the conclusion of the season, members of the show's crew reassured fans of Behrooz's safety. Deleted scenes released with the series on DVD show two fates the creators had planned for Behrooz: some scenes show a CTU team rescuing him moments before Marwan's men kill him; alternately, a scene cut from the final episode shows Behrooz being led into CTU in handcuffs. A character explains that he was found in a shipping container registered to Marwan.

• All in the Family:
  • After the later part of the 1976 season, the Bunker's next door neighbors, The Lorenzos, were never seen or mentioned again during the remainder of the series.
  • At the start of the 1976–77 season the Bunkers took in a Puerto Rican boarder named Teresa Betancourt. She was featured in several episodes, but did not return the following season. No explanation was ever given regarding her departure.

• All My Children: One of the earliest examples of the Chuck Cunningham syndrome, Joe Martin's son Bobby Martin went up to wax his skis one day in 1970 and was never seen again. The show has been known to poke fun at the incident, such as one episode in which a character ventured into the Martins' attic and found a skeleton with a shirt bearing the word "Bobby" next to a pair of skis.

• Angel (TV series): LA detective Kate Lockely was last seen in Season 2 having a heart-to-heart talk with Angel after he saved her from an attempted suicide involving pills and hard liquor. She speculates on the possible significance regarding the act, as the vampire Angel was able to enter her home without an invitation while she was still alive, yet following this scene she is never seen or heard from for the duration of the series.

• Austin Powers: Austin is partnered with an American agent named Felicity Shagwell (Heather Graham) in the second film (Austin Powers: The Spy Who Shagged Me), who he eventually falls in love with by the end of the movie. However, in the third film (Austin Powers in Goldmember), Austin is partnered up with a new agent, Foxy Cleopatra (Beyoncé Knowles), with no explanation as to what happened with Felicity.

• Babylon 5: Ambassador G'kar's assistant, Ko'Dath, disappeared without warning after the actress who played her had an adverse reaction to the prosthetics used in her makeup. B5's creator later jokingly claimed that she'd died in an off-camera airlock accident.

• Barney Miller: Barney Miller's wife Elizabeth (Barbara Barrie) featured prominently in the show's first season but had disappeared by the second. Later episodes mentioned Miller's ongoing marital problems and eventual divorce and the series that was originally written to focus on the life of its title character shifted solely to the interplay of the detectives and suspects in the police precinct where he worked.

• Battlestar Galactica (2003): Boxey, played by Connor Widdows appears in the miniseries and in one episode on season one. After being chased out of the pilots' meeting room by Colonel Tigh, he is never mentioned or heard from again (although additional scenes featuring Boxey were shot, they ended up on cutting room floor. In a commentary track on the Season 1 DVDs, the producers claim - somewhat tongue-in-cheek - that sadly, Boxey has died of cholera.)

• The Bill: The character of WPC Debbie Keane vanished in the late 1990s without explanation, and was never heard of again.

• Bonanza: Adam Cartwright, played by Pernell Roberts, was one of three sons of Ben Cartwright and was a regular character for the first few seasons of the show. When Pernell Roberts quit the show in 1965, Adam simply ceased to exist and his disappearance was never explained until the 1994 TV movie Bonanza: The Return, where his son returns from Australia.

• Boy Meets World:
  • In a first-season episode, Topanga has an older sister named Nebula Stop-the-War Lawrence. She never appears or is even mentioned again.
  • Corey's best friend, Shawn Hunter, also has two vanishing siblings: a sister who receives a brief mention in an early episode but is never spoken of again and a half-brother named Eddie who lives in the trailer park too.
  • Eric has a best friend in the first few seasons of the show, Jason Marsden. He disappears around the time when the show transitions to middle school, and is never mentioned again.

• The Brady Bunch: The girls' pet cat Fluffy appeared in only the first episode. By the second episode, Fluffy had vanished (as Carol and her daughters were all living with Carol's parents in the first episode, perhaps Fluffy was the grandparents' cat). The boys' pet, Tiger the dog, first appeared in the opening episode and continued as a regular character, but eventually disappeared without explanation. Barry Williams, who authored the book Growing Up Brady about his experiences on the show, recalls in the book that the dog who played Tiger was killed in an accident the night before the shooting of a critical scene in the episode "Katchoo". Tiger continued to appear sporadically until midway through the second season (the episode What Goes Up), but was eventually written out when various replacement dogs didn't work out. Tiger's kennel remained in the backyard to cover a burn mark on the Astroturf purportedly caused when a hot light fell onto it. While neither Fluffy nor Tiger were heard from again, they make joke cameos in a later Brady movie, in which they appear long enough for Bobby and Cindy to acknowledge their presence before abruptly running off camera with Cousin Oliver in hot pursuit, after which the children hear the screeching of car tires, shrug the occurrence off, and return to the party.

• The Brittas Empire: In the first series, Leisure Centre Manager Mr Brittas had a personal assistant named Angie (played by Andree Bernard). From the commencement of the second series, Brittas had a new assistant, Julie (played by Judy Flynn). Angie's disappearance was never explained, she was never mentioned again, and a later flashback episode showed Julie working at the centre from the beginning.

• Clueless: When the series changed networks from ABC to UPN for the 1997-98 season, Mr. Hall and Miss Geist were dropped without explanation, never to appear again. (In an unrelated topic, Doug Sheehan took over the role of Mel Horwitz at the same time.)

• Cosby: When Madeline Kahn died halfway through the show's 4th and final season, there was a special episode where the rest of the cast (appearing as themselves) paid tribute to her. However, in the show's narrative, after her final appearance early in the season, her character was never mentioned again, even though she was the best friend and business partner of Phylicia Rashad's character.

• The Cosby Show: Theo (Malcolm-Jamal Warner)'s best friend, Walter "Cockroach" Bradley (Carl Anthony Payne II), disappeared in the middle of the fourth season.

• CSI: In the pilot, Catherine Willows has two children, Lindsay and Jeremy, although only Lindsay is shown on-screen. In subsequent episodes, no mention of Jeremy is ever made.

• Dad's Army: When actor James Beck passed away in 1973, his character Private Joe Walker ceased to exist. There was no explanation for Walker's absence, and he was never referenced again throughout the series.

• Danger Man: For the first half of this spy series' second season, secret agent John Drake takes his orders from a somewhat similar figure named Hobbs. Midway through the season, Hobbs disappears and Drake begins taking orders from a succession of guest star performers.

• Days of Our Lives:
  • In 1985, Don Craig (Jed Allan, who had played the role since 1971) went out to mail a letter and never came back, and was never referred to again.
  • In 1991, Neil Curtis (Joseph Gallison, who had played the role since 1974) announced to colleagues that he had to see to some of his patients, and also disappeared without an explanation.

• EastEnders: The character of Sasha Perkins (Jemma Walker) disappeared with no explanation in 2005.

• El Hazard: The Alternative World: During the course of the series, Princess Rune Venus met and fell in love with Chibal, a farmer. The tenth episode of the series ends with a literal cliffhanger, with Chibal hanging onto the edge of a cliff. However, the cliffhanger was not resolved and the character was never even mentioned again. (In this case, due to the series run being literally cut in half, causing the creators to scramble to jam in a resolution to a plotline that was to take twice as long.)

• ER: Very prone to disappearing characters. Many supporting characters have simply been dropped without explanation, a fate known within the ER fan community as "being Bobbed", after a supporting character who vanished early in the second season.

• Everybody Loves Raymond: The character of Amy's brother was originally introduced as "Russell" (played by Paul Reubens). The character made only one appearance as the owner of a comic book store. Later, Amy's brother was shown as "Peter" (played by Chris Elliott) who was also obsessed with comic books, but had no visible means of employment and lived with his parents. Also, Debra's older sister, who was planning to become a nun, was also dealt with in only one episode, and never referred to before or since. In addition, Ray's friend portrayed by Kevin James is mentioned as Kevin in early episodes, and is later known as Doug (the name of his character in the spinoff The King of Queens).

• The Facts of Life: Originally the show centered around Mrs. Garrett and seven young girls. After the first season, Headmaster Steven Bradley, four of the girls, including Nancy, Cindy, Sue Ann and Molly (played by Molly Ringwald), were dropped from the show. They appeared in a few subsequent Season 2 episodes, but were not seen or mentioned again until Season 8.

• The Fairly Oddparents: Vicky claims to have a little brother, who is heard screaming over the phone, during one of the "Oh Yeah! Cartoons" shorts. Even in the episode that introduces her little sister, Tootie, at Vicky's house, he is not seen or mentioned.

• Family Matters:
  • Judy Winslow and Aunt Rachael disappeared from the series without explanation, with Aunt Rachael even abandoning her son (the real reason was that Telma Hopkins was given her own sitcom, Getting By, at the time). Aunt Rachael, however, returned for a few subsequent episodes after Getting By's demise. In Judy Winslow's last episode, she simply goes up to her room and never comes back down; actress Jaimee Foxworth's character was never popular, and after reducing her role steadily, she was written out of the series during the series' fourth season.
  • Several of Eddie Winslow (Darius McCrary)'s buddies disappeared without explanation. In the first two seasons, his best friend was Rodney Beckett (Randy Josselyn); in later seasons, he befriended Weasel (Shavar Ross). His longest-lasting best friend, Waldo Geraldo Faldo (Shawn Harrison), originally appeared as a sidekick to a bad guy, but then he befriended Eddie with no explanation and eventually was so popular that he became a series regular only to be dropped mysteriously a few seasons later.

• Flintstones
  • The Gruesomes who were introduced in The Flintstones were only seen in two episodes after that they were never seen or heard from again (although they were seen in The Pebbles and Bamm-Bamm Show which is set 16 or 17 years later) in fact they were actually replaced by the Frankenstones.
  • The Great Gazoo was introduced in the last season as an alien exiled from his planet however in all incarnations set after that not much is known what happened to him (he is later seen in The Flintstone prequel Viva Rock Vegas)
  • Fred has a friend named Joe Rockhead who is seen and mentioned in a lot of episodes but is neither seen nor mentioned in the last seasons.
  • Fred and Wilma have a pet sabre tooth tiger named Baby Puss who is always seen in the opening credits but is only seen in a Season 3 episode never to be seen again(in The Flintstone Kids Wilma has a kitten though), also The Rubbles buy a pet kangaroo for Bamm-Bamm named Hopperoo but in later incarnations is never seen except in the opening credits for The New Fred and Barney Show also in the The Pebbles and Bamm-Bamm Show, Pebbles had an elephant named Snooty while Bamm-Bamm has a snokesaurus named Snooty they are never seen in other incarnations set after that and even Dino wasn't part of The Pebbles and Bamm-Bamm Show who was first introduced in The Flintstones as a talking pet but changed to a barking house pet.
  • A minor case of CCS is the fact that Betty mentions having a sister who has a son however it was phased out as in the spinoff The Flintstone Kids she doesn't have a sister but a big brother. Also Mr. Slate who has had different faces and names had a daughter who was a model, an adult son who worked in his office, and a little boy named Eugene who plays for the Little League; all disappear after one episode.

• Franklin: This program displays all forms of the syndrome. A number of characters have appeared only one time and were never seen again. Others are bizarrely only seen from time-to-time, despite the fact that Franklin and his friends attend kindergarten and therefore they should be in class. In another case, a character was seen in an early episode then reappeared in the third season and appeared to be completely unrecognized.

• Futurama: The X-1 robot is introduced in the episode Obsoletely Fabulous to help the crew of Planet Express, and was absent from the (final) two episodes that followed.

• Garfield: The character of Lyman, Odie's owner was inexplicably dropped in the first few years of the comic strip. Odie suddenly became Jon's pet.

• Gimme a Break!: Uncle Ed, the Chief's older brother, mysteriously disappeared.

• The Golden Girls: Coco, a gay housekeeper who helped out in Blanche's house (where the women lived and the series primarily took place) disappeared after the pilot episode, with no further mention.

Carl turns out to have a lung condition and the newly married couple move away to Arizona, hoping it'll improve his health. After being gone for a season, Florida moves back and no one explains where Carl went or mentions that Florida ever remarried.

• The Greatest American Hero: Ralph Hinkley's son Kevin went from being featured semi-regularly to appearing rarely to only being mentioned in passing by mid-season 2, after which he is never seen or heard from again (though it is possible that his mother somehow gained custody during events never shown onscreen).

• Happy Days: Chuck Cunningham.
  • Also Fonzie had a young nephew named Spike who liked Joanie and was a mini clone of Fonzie. However, he is not seen after the introduction of Chachi.
  • Marsha who was a carhop at Arnold's vanished after the second season.

• Hey Dad: Nudge, the Kelly family's next-door neighbour and regular character vanished between seasons. No mention was ever made of the character again. While almost the entire cast would leave the show during its run, the departure of Nudge is the only case where no reason was given.

• Hey Arnold:Some minor examples are Mr. Smith a mysterious housemate who disappears and Arnold's coach's son Tucker who was absent even in his parents remarriage.

• Home Alone: Although it is a movie an severe case of the Chuck Cunningham Syndrome is in this movie in two installments Kevin McAllister (Macaulay Culkin) has two brothers (Buzz and Jeff) and two sisters (Megan and Lainie), however in the fourth installment Buzz and Megan are his only siblings who both seem like a combination of the other missing siblings and themselves.

• Hotel: In the pilot Bette Davis plays Laura Trent, owner (or majority owner) of the hotel. However in the series that followed her sister-in-law Victoria Cabot (Anne Baxter) is at the helm. It is explained in the script she is minding the hotel while Laura takes care of troubled hotels she owns elsewhere. However in subsequent seasons Laura never returns; Victoria (rather than Laura Trent) is later said to have hired the general manager Peter McDermott (James Brolin) even though he was in place prior to the events of the pilot. Victoria is also said to share ownership with her family business Cabot Inns.

• JoJo's Circus: Various characters appear from time-to-time in JoJo's clown class or as friends of hers, then disappear with no explanation.

• Just Shoot Me: In the first season, Maya had a goofy roommate named Wally, played by Chris Hogan. He usually had one scene per episode, and in one scene slept with an age-phobic Nina Van Horn. After the six episodes of the first season, Wally was never seen nor mentioned again. Some of Hogan's scenes were cut from re-runs as well. Fans of the show have some alarming theories as to what became of Wally. 1

• The King of Queens Carrie's sister Sara Spooner, played by Lisa Rieffel, appeared in only a few episodes (including the pilot) during early first season as a ditzy struggling actress who lived with her father Arthur. In the pilot, she moves, along with Arthur, into Doug and Carrie's home after her stepmother (Arthur's third wife) dies and their home burns down while Arthur is cooking with an old electric stove. Originally she moves into a spare bedroom, which a season later, becomes Carrie's home office. However in later episodes, it appears that she is not living with Doug and Carrie and may have moved out. Ultimately, Rieffel was let go from the show after writers ran out of ideas for her role and has not been mentioned since. Doug's best friend Richie Iannucci, played by Larry Romano, only appeared during the show's first two seasons and one episode (Paint Misbehavin') in the third season. He has not been heard of since his last appearance. Richie was apparently replaced by Doug's cousin Danny, played by Kevin James' real-life brother Gary Valentine. Doug also has a sister, Stephanie, played by former talk-show host Ricki Lake, who appeared in a few episodes during the third season. She has also not been heard of since.

• Life With Bonnie: The Molloys' oldest child, Samantha, disappeared from the show after the first season. According to series star Bonnie Hunt, this was due to "creative differences." The daughter seemed to have been replaced by a neighbor's son whose parents are never seen.

• Living Single: Regine Hunter (Kim Fields) did not appear in the final three episodes of the series.

• The Lucy Show: When the series began Lucy had two children Chris and Jerry. In 1965 Lucy moved to Hollywood and her daughter Chris was mentioned to have gone to college and afterwards was never mentioned again. Within a few episodes of the 1965/66 season Jerry went to military school and at first rarely mentioned the he was never mentioned again.

• Mad About You: During the first half of the first season Paul Buchman had a college buddy named Jay Selby. Selby was basically Paul's sidekick, though Jamie appeared not to like him much. References were made to their past adventures which included double-dating. Selby's character was never really developed and written out of of the show midway through season #1. He went off to escort his grandmother to the museum and was never heard from again. His role on the show was replaced by Paul's cousin Ira. In a fifth-season episode, Selby's sudden disappearance is referenced by Paul, who's having a conversation with Jamie about how they don't seem to have that many friends: "Like Selby, what the hell happened to him?"

• Mama's Family: During the first two seasons of the show, Mama's son Vinton had two teenage kids from his first marriage -- Sonya and Buzz. When the show returned for its third season, both were gone without explanation, with only one fleeting reference made about them, during the episode back. They were not spoken of at all for the remainder of the series. In the final season, while Vint and his second wife Naomi awaited the birth of their first child, it seemed to be implied that Vint had no other children.

• Married... with Children: Seven runs away to live with the D'Arcys and is never seen again (The producers of the show realized they had made a mistake in introducing his character; his face was later seen on a milk carton). Also, the character Luke Ventura was never seen after the 1st season and was eventually replaced by Griff, although he was referenced one final time. Many NO MA'AM characters were dropped, notably the character Rodger.

• M*A*S*H:
  • Spearchucker Jones appeared during the first season as a doctor at the 4077th and the fourth tent mate in the Swamp. He quietly disappeared during the first season when the producers were made aware that in fact, there were no black surgeons in United States Army M*A*S*H units during the Korean War.
  • Later on in the first season, the anesthesiologist Ugly John Black, who played a rather prominent role in the series, also disappeared. No explanation was ever given for his departure. However, the character of BJ Hunnicut was scripted to reference Ugly John in a much later episode, but the line was cut out of the final cut. BJ was scripted to write a letter to home, in which he told his wife that "It seems like they're all leaving us. Even Ugly John got shipped home."
  • Odessa Cleveland played a Afro-American nurse in the first season & appeared in the MASH Christmas Episode. However she was never seen again in the series.

• Matlock: Both of Ben's daughters Charlene Matlock and Leanne MacIntyre were written out of the show and were only mentioned once (Charlene also featured on a flashback) after their departure. Also, Ben's assistants Tyler Hudson, Cassie Phillips, Michelle Thomas and Conrad McMasters as well as his neighbour Les Calhoun left without explanation.

• My Family: In the first series, dentist Ben Harper (Robert Lindsay) had an assistant named Brigette (Daisy Donovan), who did not reappear for Series 2. Throughout the rest of the show, Ben had a series of different, short lived assistants.

• My Three Sons: For a number of seasons, Mike Douglas (played by Tim Considine) was the oldest son. When Considine left the series, Ernie was adopted so that there were still three sons. And, while Ernie's adoption was referred to throughout the series, Mike was never mentioned again, and Steve Douglas mentioned several times that he had three sons, never four, and that Robbie was the oldest.

• New York Undercover: The lieutenant, played by Patti D'Arbanville, was dropped from the show without any explanation after a third-season finale that killed off two other characters.

• The New Tomorrow: The fearsome and bossy character of Jag suddenly dissapears, and no explanation is made.

• Nip/Tuck: The pilot episode featured a character named Rosa who was the maid for the McNamaras. She has not been seen since and no explanation has been given for her absence. More noticable would be Grace Santiago (Valerie Cruz) who was a main character the first season. She just vanished by the second season and no one has mentioned her since.

• One Life To Live: Carlotta Vega's adopted son Eli Traeger disappeared in 1998, never to be spoken of again.

• Oz: In episode 4 of the first season, Nino Schibetta's cellmate and sidekick, Joey D'Angelo, goes to the infirmary after being assaulted in the prison kitchen. He never comes back to Em City, nor is it explained what happens to him, although his injuries were not life-threatening.

• Roseanne: Bonnie Sheridan, a coworker of Roseanne's at Rodbell's played by Bonnie Bramlett, disappears without further mention at the end of season 4. Many minor characters from Roseanne's various places of employment before the establishment of the Lunch Box would be written off in a similar fashion. Also, Crystal Anderson, played by Natalie West, was dropped from the main credits in season 4 and made only sporadic appearances thereafter.

• Sabrina, the Teenage Witch:
  • Between the first and second seasons, the characters of Jenny Kelly (Michelle Beaudoin) and teacher Eugene Pool (Paul Feig) were dropped from the series, with no explanation of their absenses.
  • During the fourth season, two semi-recurring characters were "witch hunter" Brad Alcerro (Jon Huertas) and trainee witch Dreama (China Shavers). Both were dropped for the fith season, again with no explanation.
  • The character of Miles Goodman (Trevor Lissauer) disappeaered without explanation between seasons six and seven.

• Saved By The Bell:
  • When Zack, Screech, and Lisa graduate from junior high to high school, along with an inexplicable shift in setting from Indiana to California, came the unexplained disappearance of best friends Nikki (Heather Hopper) and Mikey (Max Battimo). Also, the characters of Carrie Bliss (Hayley Mills), formerly the prime focus of the series, as well as Milo Williams (T.K. Carter) and Tina Paladrino (Joan Ryan) were all dropped without any explanation, and were never mentioned again.
  • During the gang's senior year, Jessie and Kelly are present for only about half the episodes. The first episode without them contains a quick scene in which Zack speaks to them on the phone but they are neither seen nor heard. The other half of that season's episodes do not feature these two main characters, but instead introduce a new character named Tori.
  • The final "Graduation" episode had already been shot when the network ordered additional episodes. Tiffani Thiessen and Elizabeth Berkley were attached to other projects by that time, necessitating the creation of a replacement character Tori, played by Leanna Creel. The Tori episodes aired in the middle of the other final season episodes to sidestep continuity problems (though the disappearance and later reappearance of Kelly and Jessie, and vice versa for Tori, went unexplained).
  • In the spin-off Saved by the Bell: The College Years, Zack, Screech, and Slater move into a co-ed dormitory populated by three new female leads, one of whom is Danielle Marks, portrayed by Essence Atkins. However, in the second episode, Thiessen's character Kelly returns to the cast, and Danielle disappears without a trace and only a passing mention to a girl transferring out.

• The Secret Life of Us: A large portion of the cast left the series at the end of the third season, and while the final episode revolved around the election of Sibylla Budd's character to parliament, the characters of Dan Spielman, Gigi Edgley, Spencer McLaren (a founding member) and Nina Liu disappeared without warning. The fourth season began with an almost entirely new cast and without explaining the disappearances of four key characters. The series was axed three episodes later.

• Seinfeld: Originally, the regular female character of this series was to be a waitress at the diner frequented by the show's other regular characters. This character is featured prominently in the pilot episode, but is not seen again in subsequent episodes. After production of the pilot, the waitress character was abandoned and replaced by the character Elaine, a friend and former girlfriend of Jerry. Also in the pilot was Kramer's dog, who was never seen again. There was also an off-screen variation of CC syndrome when it was mentioned in an early episode that George has a brother, but he is clearly an only child by the time we meet his family. In the 'Chinese Restaurant' episode, Jerry mentions having a sister, who is never referenced again.

• Sesame Street: After Northern Calloway's death in 1990, his character, David Robinson, was never referenced to again (although when Will Lee died prior to that, there was a special episode stating that Mr. Hooper was dead).

• Sex and the City: The character "Skipper", a friend of Carrie's and a short-lived boyfriend of Miranda, disappeared after the second season. Though he was never a big character, he was in quite of few episodes and relationship with Miranda. Though most of the guys are never seen again, he was friends with Carrie, so it seems odd that he was just cut out of her life. One reason for his 'demise' may be that he was a character from the book that the show was based on, and by that time the producers were probably trying to take the show in its own direction, and stop taking situations from the book.

• The Snorks: Allstar's best friend, an orange snork named Dimmy Finster, disappeared midway through the 1985 season and was never mentioned again (yet he still appeared in clips for the 1987 season's opening credits).

• South Park: In several early episodes, Kenny has an unnamed older brother. After the third season episode Spontaneous Combustion, he is not seen again, until the recent ninth season episode Best Friends Forever where Kenny's brother can be seen in a few shots.

• Space: 1999: Between the first and second seasons, Paul Morrow and Ben Kano disappeared from Moonbase Alpha without any explanation, a particularly glaring omission since there was nowhere they could have gone (both were let go by new producer Fred Freiberger in favor of new characters Tony Verdeschi and Maya in an effort to make the show's appeal a little broader). Victor Bergman (Barry Morse) also vanished between the first and second seasons. A throwaway line about a spacesuit malfunction was written, but not aired. Morse left due to a contract dispute with Freiberger. (The Moonbase Alpha Technical Notebook timeline of the series not only includes Bergman's spacesuit malfunction but also attributes Morrow and Kano's disappearance to an Eagle crash).

• Spin City: At the end of the fourth season, four principal characters departed: Flaherty, Nikki Faber (Connie Britton), James Hobert (Alexander Chaplin) and Janelle Cooper (Victoria Dillard). But while Fox's departure was set up over the course of several episodes, and he made guest appearances in later seasons, none of the other characters were ever mentioned again. Stacey Paterno (Jennifer Esposito) and Angie Ordonez (Lana Parilla) similarly vanished without comment at other points in the series' run.

• SpongeBob SquarePants: In the first season SpongeBob had a pet scallop sitting next to his bed and it was never seen again after 2 episodes.

• Star Trek: Deep Space Nine: In several early episodes, a Starfleet security officer named Primmin is part of Sisko's crew, but he disappears without trace. In another example of Chuck Cunningham Syndrome, at the start of the third season, Martha Hackett joined the cast as T'Rul, a Romulan assigned to DS9 for the purpose of supervising Starfleet's use of cloaking device technology. T'Rul appeared in the opening two-part episode of the season, after which the plot point regarding Romulans requiring supervision of the cloaking device mysteriously vanishes.

• Star Trek: Enterprise: During the first season, Kellie Waymire made several appearances as a young crewmember named Elizabeth Cutler. Despite her brief appearance, the character became extremely popular with fans. After Waymire became involved in a TV series project and other productions, she was no longer available to play the role, although the character continued to be mentioned from time to time up until the start of the third season. Waymire died in 2003, but the series did not establish what happened to the character. Similarly, another popular recurring character, an Engineering assistant named Rostov, appeared early in the series but vanished without trace after the start of the fourth season; he was "name-dropped" numerous times thereafter however.

• Star Trek: The Next Generation:
  • During the first season, four different actors were seen playing the Enterprise's chief engineer at various times. At the start of the second season, Geordi La Forge had become chief engineer, and these characters (Argyle, Logan, MacDougal and Lieutenant Commander Leyland T. Lynch) were never heard from again.
  • During the second season, Diana Muldaur joined the cast as Dr. Katherine Pulaski, replacing Dr. Beverly Crusher, played by Gates McFadden as the Enterprise-D's chief medical officer. Crusher's absence is explained by her decision to leave the Enterprise to head Starfleet Medical. At the beginning of season three, McFadden returns to the cast, and Muldaur is gone. Dr. Pulaski's absence remained unexplained for the remainder of the series' run.
  • A doctor on board the Enterprise-D, Dr. Selar (played by Suzie Plakson) was seen only once in the second season. Even though she was never seen again, she was subsquently referred to in dialogue and paged over the ship's PA system. Plakson went on to portray K'Ehleyr in the series.
  • Several secondary characters were introduced with the implication of becoming regulars, only to disappear after one or two appearances. Most notably, this occurred with Ensign Sonya Gomez (Lycia Naff), introduced as a naive new member of LaForge's Engineering staff (and potential love interest for LaForge), and Ensign Robin Leffler (a pre-stardom Ashley Judd), a brilliant young officer with a rule for everything. Both characters would later be revived in the Star Trek novels.

• Star Trek: During the first season, Janice Rand was a regular, serving in the capacity as the captain's yeoman and potential love interest for Captain Kirk. She mysteriously disappeared halfway through the season and, although she has appeared in four of the Star Trek movies and an episode of Star Trek: Voyager since, no explanation has ever been given for her departure (William Shatner claims that Grace Lee Whitney was let go because of serious drug and alcohol problems; while that was true, the producers have said that they just didn't think it was a good idea for Kirk to have a love interest on the ship).

• Stargate SG1: Dr Sarah Gardner, ontime love-interest of Daniel Jackson, served as a romantic interest and recurring villain in seasons four through seven. In season seven she was rehabilitated by the humans of Earth, and presumedly ready to play a romantic role again. She was last seen in the SGC infirmary, and has not been mentioned in the two seasons since.

• Stargate Atlantis: First season reoccuring villain Sora was captured by the humans of Atlantis in the episode "The Eye". She was never mentioned again and was presumably returned to her people as an offscreen part of a deal negotiated in the episode "The Siege, Part 2".

• Step By Step:
  • The youngest Lambert boy on the show, Brendan, saw his role reduced during the last few years of the show until he was completely dropped from the show during the last season without explanation.
  • In the first season, Carol owns a beauty salon attached to the Lamberts' house. The beauty salon employs two women, Carol's mother and sister, who are also main characters. After the first season, the two women are completely dropped.

• Taxi: Cabbie John Burns (Randall Carver), a displaced midwesterner, disappeared after one season of being a regular character. Nothing was mentioned about it on the show, but the producers realized the character had run its course, and most jokes associated with his character could easily be transferred to Tony Banta.

• That's My Mama:Two old fellows who visit Clifton's Barbershop, Wildcat (Jester Hairston) and Josh (DeForest Convan) disapeared after the first season, and was never mentioned again.

• That '70s Show: Donna's younger sister, Tina, is shown once and never mentioned again. Donna also apparently had an older sister, Valerie, who was mentioned once but never seen or mentioned again. Eric also had an older sister who featured prominently for two seasons, vanished for season three, returned (in a few, brief, episodes), played by a different actress. She has not been heard or seen since, though the cast will occasionally reference her absence.

• Three's Company: Chuck Cunningham syndrome appeared three times in Three's Company:
  • Lana Shields (Ann Wedgeworth) was added to the show at the beginning of the fourth season but soon disappeared several episodes later when the show's writers realized they had run out of ideas for her.
  • Chrissy Snow (Suzanne Somers) was the original blonde girl on the show. She moved temporarily during the fifth season with the apparent intention of coming back, but was never heard from again afterwards (she was forced out of the show during a failed attempt to hold out for more money).
  • Cindy Snow (Jenilee Harrison), Chrissy's cousin, was Chrissy's first replacement on the show. She disappeared during the sixth season after an argument with Janet and was never heard from again.

• The Torkelsons: During their move from Oklahoma to Seattle (and the show's name change to Almost Home), the family mysteriously loses two children, Steven Floyd and Ruth Ann.

• UFO: At the mid-point of this cult science fiction series' first and only season, several major cast members drop out without explanation, most notably the character of Col. Alec Freeman (George Sewell) who is replaced as the first officer of the secret organization SHADO by Col. Virginia Lake (Wanda Ventham). (The dropping of several characters was sparked by a five-month break in production while the series changed studios, during which time several lead actors obtained roles in other series.)

• The West Wing: The West Wing has an especially severe case of Chuck Cunningham Syndrome. Due to the show's large pool of secondary and tertiary characters, characters tend to disappear for no apparent reason. The show has even developed its own term for Chuck Cunningham Syndrome, "Mandyville", named for the first character to depart in such a manner.
  • The character of Mandy Hampton was dropped after the first season without explanation, though the show's creator, Aaron Sorkin, has said that she was dropped because the character had run her course and Moira Kelly's departure was amicable. "Mandyville" is named for Hampton.
  • Ainsley Hayes (Emily Procter) vanished slowly from semi-regular appearances in season 2, and her position in the White House was taken over by Matthew Perry's character in season 4. A later episode had Josh Lyman lamenting that Republicans who looked like Ainsley Hayes weren't seen around the West Wing any longer since she took a private sector job.
  • During Season 4, Toby Ziegler, the White House Communications Director played by Richard Schiff, fathered twins out of wedlock with his ex-wife, Congresswoman Andrea Wyatt (Kathleen York). In the episode "Commencement," Wyatt gave birth to Huck, named for her grandfather, and Molly, for the Secret Service agent killed while protecting First Daughter Zoey Bartlet. Once Aaron Sorkin left the show after "Twenty-Five," the fourth season finale, producer John Wells ignored the twins, using them only briefly in season 5 ("Jefferson Lives") and seemingly forgetting them altogether in Season 6. They were mentioned briefly in Season 7 when Toby's lawyer was listing his responsibilities, and again later, when Josh asks Toby where they are staying. The West Wing does focus on jobs rather than personal lives, so this Syndrome incident makes some sense. Wyatt (York) also fades from view.
  • Elsie Snuffin (Danica McKellar), Will Bailey's (Joshua Malina) sister. He insists that she join him when he comes to work in the West Wing since they are a team, she disappears without explanation after around 10 episodes. She is not mentioned again.
  • Jordon Kendall (Joanna Gleason), Leo's lawyer, is set up as a romantic interest for him early in Season 4. A couple of episodes later, Bartlett asks Leo how their romance is going, and he responds that it's going well. No mention of her is ever made again.

Chuck Cunningham syndrome - Examples of Chuck Cunningham syndrome where 'Chuck' returns

• Babylon 5:
  • Ambassador G'Kar's second diplomatic attache, Na'Toth became a Chuck Cunningham. The character was played by three seperate actresses: Susan Kellerman, Julie Caitlin Brown, and Mary Kay Adams. Kellerman quit after her first day of shooting, due to issues with claustrophobia. Brown replaced her, and played the role for the rest of season 1. However, she quit at the end of the season, due to issues with the prosthetics and make-up. Adams played the roll of Na'Toth for part of season 2. Although the character was written out, no official explaination was given to her dissapearance. Viewers assumed the character died during an attack on the Narn homeworld. However, during the fifth season, Na'Toth was found in a prison on the Centauri homeworld, where she had been detained and then forgotten about.
  • In a more minor case of Lazarus Chuck Cunningham syndrome, the station's assigned telepath, Lyta Alexander was replaced, after the pilot, by a different character, Talia Winters. Unlike the other replaced characters from the pilot (see below), Lyta returned in a recurring role in the second season, and would go on to play a significant role in the series.

• Boy Meets World:
  • Corey's sister Morgan disappears after the second season. During her absence she is never mentioned. When she reappears two seasons later as a new actress, after Corey mentions her name and how unobtrusive she has been by "staying in her room", she comes down the stairs saying "That was the longest time out I've ever had."
  • The character of Stewart Minkus, a classmate of Cory and Shawn's in elementary school, disappears after the first season, and is never mentioned again until the episode in which they graduate from High School. When he reappears, Cory and Shawn ask where he's been. Minkus responds by pointing towards the camera, and saying "Over there, on the other end of the school." The boys respond that they don't go to that end, as people have been known to never return. Minkus then calls out in that direction to Mr. Turner, a teacher who was likewise dropped from the show after being a regular.

• Days of Our Lives: At the beginning of the series, the Hortons had only four children. A fifth child, Tom Jr., was added in 1967 with the explanation that everyone thought he "died" in the Korean War. He returned to Salem and was a key character on the show until 1972, when he went upstairs to take a nap and didn't come back. He finally returned in 1975; the actor found himself walking down the Horton staircase in his first scene back, announcing "What's for dinner? I'm famished!".

• Doctor Who:
  • In the twentieth season an apparent new companion, Kamelion, was introduced in the story The King's Demons. Kamelion, a shape-shifting android, departed with the Doctor and his companions at the end of the story, but was not seen in subsequent episodes, apparently due to problems with the robot prop. Kamelion did make a sudden reappearance (with no real explanation as to where he'd been) a year later for the Fifth Doctor's penultimate story, Planet of Fire.

• The Dukes of Hazzard: "Replacement cousins" Coy and Vance, who were the main characters during the series' 1982–1983 season. Series stars John Schneider and Tom Wopat, who played Bo and Luke, had left in 1982 due to a contract dispute, forcing the producers to hire replacement actors Byron Cherry and Christopher Mayer. A line was used referring to them as having joined the NASCAR circuit, meaning had they stayed away, they would have been examples of Near Chuck Cunningham and not true Chuck Cunningham syndrome. Coy and Vance were never popular with fans, and the ratings immediately sank. When Schneider and Wopat returned in early 1983 after their grievances were resolved, Coy and Vance were immediately written out and never referred to again.
• Star Trek: The Next Generation: The popular character of Ensign Ro Laren (played by Michelle Forbes) was introduced during the fifth season and appeared in numerous episodes. The character proceeded to disappear from the series, appearing only once during the sixth season and then finally received a "farewell" episode of sorts near the end of TNG's seventh and final season. Ro's absence is said to be due to her attending training off-ship.

• Star Trek: Voyager: When Voyager began its run, Josh Clark appeared in a recurring role as Lt. Joseph Carey, the person passed over for the position of Chief Engineer in favor of B'Elanna Torres. Despite his numerous appearances in the first season, from the second season onward he was promptly forgotten. Curiously, he was prominently featured in a few flashback episodes in the fifth season, but never featured in the present (as though the writers figured he had been killed off, like many other recurring characters). He finally reappeared in the seventh season in one of the last episodes as a featured guest star, only to die in the middle of the episode. Many fans were upset at the thought that Lt. Carey was brought back only to be killed off.

• That 70's Show: Leo disappeared after season 4. However in the eighth, and final season he returned with out any explanation. (Tommy Chong was dropped by the show after being convicted of drug paraphenalia sales on the Internet in 2003, but was obviously rehired).

• The OC: Marissa originally had a younger sister in season one, but with few lines and a very minor role. As of season two she has disappeared, although she is occasionally referenced as being in boarding school. She's coming back as a vamp.

• The West Wing: While some characters have disappeared and either never returned or been replaced by a new character, some characters have returned to the series after prolonged absences with no explanation. White House Counsel Oliver Babish (Oliver Platt), for example, appeared regularly on air during the third season when President Bartlet was facing legal troubles and then disappeared. Then in the seventh season, he reappeared during an investigation of a security leak. The implication is that he was there doing his job all along unseen off camera. Other characters have similarly gone on and off camera during the show, in some cases being referred to by the on air characters.

Chuck Cunningham syndrome - Examples resembling Chuck Cunningham syndrome where the absence is briefly addressed

• Are You Being Served?: Several characters disappeared during the run of this series, including Mr. Mash, Mr. Grainger, Mr. Goldberg, Mr. Lucas, Mr. Grossman, Mr. Klein, and Young Mr. Grace. These disappearances were, perhaps, not unexpected. A couple of these characters were elderly and it was explained that they died. The disappearance of the others could simply be attributed to the fact that the characters worked in a retail setting, where employee turnover is a simple fact of life. Further, the show's episodes were self-contained and events of prior episodes were rarely mentioned in subsequent episodes, so the fact that departed characters were not mentioned after they left is hardly notable. The main reason for the inclusion here is that all these characters departed and were replaced between seasons meaning the original character had no farewell scene and the circumstances of their departure not shown, and the replacement had no formal introduction.

• Babylon 5:
  • The pilot episode features two characters who never appeared again: First Officer Laurel Takashima, and medical officer Dr. Benjamin Kyle. After the pilot the characters were replaced by Susan Ivanova and Dr. Stephen Franklin, respectively. A few references were made later in the series to Dr. Benjamin Kyle being reassigned to work on Earth after his direct encounter with a Vorlon, but no further mention was made to Laurel Takashima.
  • In addition, the second season began with the show's main character, Jeffrey Sinclair absent, with the mysterious explanation that he had returned to Earth for reassignment. This was an amicable decision made jointly by the actor, Michael O'Hare and the series' producers. In a later season, the character's story arc was skillfully resolved with a few guest appearances by O'Hare, culminating in a two-parter, War Without End.

• Barney Miller:
  • Det. Nick Yemana disappears from the series following the Jack Soo retrospective episode. Jack Soo had died, but it's never made explicit what happened to his character. Characters occasionally make reference to Nick, generally in a wistful context, but whether he died, had a horrible accident or simply got another job is unclear.
  • Meanwhile, the prominent character of Det. Chano Amengual disappears unceremoniously near the end of the second season. A few years later, when a female detective is unexpectedly assigned to the precinct, Capt. Miller looks into the matter and explains with bemusement that she has been sent to replace the long-absent Chano.
  • Finally, several detectives who made sporadic or even single appearances during the first season are dramatically erased from the roster board as Capt. Miller announces they were laid off due to departmental cutbacks.

• Becker:
  • The character of Reggie Kostas (Terry Farrell) was axed between the 4th and 5th seasons. In the first episode of Season 5, it is explained that Reggie left town after "hitting rock bottom" due to sleeping with Becker (Ted Danson) at the end of the 4th season.
  • Bob (Saverio Guerra) left the show between Seasons 5 and 6. He is said to be "on vacation" in the first episode of Season 6 but is never referred to again afterwards.

• Coronation Street: Linda Baldwin (Jacqueline Pirie) suddenly disappered without warning, due to the actress refusing to continue her role. The disappearance led to a big storyline about what happened to her. Despite the characters believing she crashed her car into the water, Linda sent a note to her husband, Mike, telling him that she was safe in Ireland.

• Doctor Who: During the course of this series, the Doctor traveled with many companions. One of these, Dorothea "Dodo" Chaplet, disappears from the programme during the serial The War Machines. Though Dodo does send a farewell message to the Doctor at the end of The War Machines, she herself does not appear for a farewell scene.

• Dynasty: In seasons 4 and 5 Amanda Carrington was played by Catherine Oxenberg and she was one of the major characters. In Season 6 she was replaced by Karen Cellini, and Amanda became only a background character. In seasons 7 and 8 Amanda disappeared altogether with only a brief mention on the show that she was living in Europe.

• EastEnders:
  • Soon after joining the show, actor Dalip Tahil who played Dan Ferreira was deemed an illegal immigrant, and deported from the UK. In the show, his children often mentioned his disappearance, but exactly what happened to him was never mentioned.
  • Actor Christopher Parker quit the show abruptly after a suicide attempt. It was briefly addressed that his character, Spencer Moon had been in some trouble with the police and was sent to live with his cousin Maxwell by his brother Alfie.

• Friends: Ross's son Ben is rarely referenced in later seasons, even though he was a frequent character. This may have something to do with the fact that the actor playing Ben aged faster than his TV character should have. He is referenced occasionally and in the episode where Rachel gives birth to Emma, Ross's father says Emma is going to be Ross's first child to which Ross replies "What about Ben?".

• Grounded for Life: Youngest son Henry Finnerty vanished in the final season of the show since actor Jake Burbage had moved away with his family. However, Henry was still occasionally mentioned by his parents, just never seen.

• Law & Order: Captain Donald Cragen (Dann Florek) and ADA Paul Robinette (Richard Brooks) mysteriously vanished after the show's third season. The show was initially an all-male cast for the first three years, but NBC wanted to add women on the show. So the "boys' club" had to be disassembled; otherwise, as then-NBC head Warren Littlefield told series creator Dick Wolf, the show would be canceled.
  • Cragen's disappearance was not explained until the fifth season episode, "Bad Faith," in which we learn that he heads the Anti-Corruption Task Force. Florek would later reprise his Cragen role for Law & Order: Special Victims Unit.
  • Brooks reprised his Robinette role in a later season as a guest star, acting as opposing counsel. Robinette explains that when his boss had asked him "Are you going to be a lawyer who is black, or are you going to be a black man who is a lawyer?" his answer had changed, and he found new work as a rights advocate.

• Lizzie McGuire: The character of Miranda Sanchez (played by Lalaine) was missing from the show's final season for several episodes, presumably because Lalaine was busy working on the Disney Channel Original Movie You Wish!. Other characters would cover up by this by making excuses such as, "She's sick," or, "She's in Mexico visiting her aunt."

• Mama's Family:
  • During the first two seasons (in which the show was owned exclusively by NBC), the characters of Buzz and Sonja were regulars. After the second season, however the show left NBC and went into first-run syndication. During this time, drastic cast changes were made. Vinton's children, Buzz and Sonja, never very popular with fans, were dropped at once. A subsequent episode established they had gone away to college. However, they were never referred to again after that.
  • Thelma's two daughters, Ellen (Betty White) and Eunice (Carol Burnett) and Eunice's husband, Ed (Harvey Korman), were regular guest stars who were featured prominently during the first two seasons of the show. After the show went into first run syndication, Ellen was seen only once more. Her absence was explained as not being forgiven for missing Aunt Fran's funeral. However, after her final appearance in the third season, she is never mentioned again. Eunice and Ed are never seen again after the second season, although it was explained that they moved to Florida, leaving their son Bubba behind and forcing Thelma to take him in (Eunice does call Thelma in one syndicated episode, but the voice was of a different actress).

• Mighty Morphin' Power Rangers: The original Red, Yellow, and Black Rangers quit due to invitations to a peace conference (in reality, they were fired) and were replaced in the beginning of Season 2. Similarly, the Pink Ranger quit halfway through season 3. At the beginning of Power Rangers Turbo, Ernie, the owner of the Juice Bar, abruptly left the show. His disappearance was briefly explained by Lt. Stone, who said that Ernie was called up by his foreign service unit. This also explains the abrupt role change for Lt. Stone, who, after getting his job back as a police officer in the Turbo movie (and indicating being pleased to have gotten his police job back), abruptly left the force again to run the Juice Bar. In reality, Richard Genelle, the actor who played Ernie, left due to extremely poor health. [1]

• Sabrina, the Teenage Witch:
  • Valerie Birkhead (Lindsay Sloane) and Libby Chessler (Jenna Leigh Green) were dropped between the third and fourth seasons. The fourth season premiere explained that Valerie had moved to Alaska, and Libby had gone to boarding school.\No mention of either character was made again throughout the rest of the series.

• Sealab 2021: At the end of season three, Captain Murphy was removed from the show. The in-character reason was that Murphy went to fight in the Great Spice Wars. The real reason was that Harry Goz (the voice of Captain Murphy) had died of cancer. After attempting to find a replacement voice for the character, the creators decided to go with a new one, Tornado Shanks, voiced by Michael Goz, Harry's son.

• SeaQuest DSV: Dr. Wendy Smith (Rosalind Allen) and Sensor Chief Miguel Ortiz (Marco Sanchez) disappear at the end of the second season. Although no mention is made of their disappearance, it is presumed that they were killed during the second season finale, "Splashdown."

• The Simpsons:
  • The therapist Dr. Marvin Monroe was dropped from the series with no explanation because the cast all hated the sound of his voice (Harry Shearer has also said it was hurting his throat). The first reference to the character's departure was the appearance of "Marvin Monroe Memorial Hospital" in one episode. In an episode about the show's anniversary, it was implied that Marvin Monroe was one of two characters that died at the time (the other character was Bleeding Gums Murphy). However, he reappeared in a later episode claiming he had been "very sick" during the time he was missing, it was produced as a parody of what happened.
  • After guest voice actor Phil Hartman was murdered in 1998, his two characters, Lionel Hutz & Troy McClure, were dropped from regular appearances, without explanation. They both have made appearances in clip shows and in crowd scenes, but never in major roles. As a tribute to Hartman, two pages in the Simpsons episode guide Simpsons Forever! were used as a tribute to McClure's career in entertainment, but nothing is explicitly said about his fate.
  • When regular guest Doris Grau died in 1995, her character, Lunchlady Doris, was similarly "retired", though occasionally mentioned in later episodes.
  • The elementary school band teacher Mr. Largo is shown in the show's opening, and was originally intended to be a fairly prominant character, but was instead abandoned for much of the series' duration. Recently he was brought back for a small cameo.
• Stingers: In Series 1, Detective Kaye Kelso was abducted and nearly died during an undercover operation. Kaye Kelso went on sick leave to recover, but she never returned to the undercover unit, and quickly vanished into obscurity.

• SuperFriends: The Superfriends had three teenage sidekicks, Marvin, Wendy and WonderDog, who disappeared after the 1973 season; however, their absence is later explained in the SuperFriends comic in 1976.

• The Tick: American Maid, one of the more competent heroes of The City, did not appear in seasons two or three, although she was still often referred to in dialogue.

• Walker, Texas Ranger: Mid-Eighth season former Texas Ranger and Bar Owner, C.D. Parker had mysteriously disappeared from the show, starting with the episode Vision Quest. It has been mentioned that he won a round the world cruise. In the Eighth season finale it was mentioned that he was going to attend the wedding of two of the main characters, Cordell Walker and Alexandra "Alex" Cahill, but his plane was delayed and couldn't make it. In an early episode of the final season it was mentioned that he was catching an illness, but at the end of that episode the rangers get a call saying that C.D. has died. In the two-part series finale episodes, it was revealed that C.D. was actually killed by poison. The ones responsible were the same antagonists that the rangers were currently facing. This was done as part of the antagonists plan to exterminate all the Texas Rangers in Ranger Company B.
  • The reason why Noble Willingham, the actor who played C.D. Parker, left the show was to run for Congress.

• Welcome Freshmen: In the third and last season, the sketch format of the show was changed to following a single story. Subsequently, two characters leave. In the first episode of the season we find out that Merv has gone to college after finishing the ninth grade (he's made fun of because he has to be a freshman again) and, Tara has gone to live in a biodome for a year. Neither of them are ever spoken of again after that episode.

Chuck Cunningham syndrome - Chuck Cunningham syndrome in reverse

Perhaps because it creates even more credibility problems, producers are much less likely to suddenly introduce characters whose presence should have been at least alluded to or explained earlier. But it has happened on a few occasions.

• Battlestar Galactica: Wallace Gray, supposedly a key player in President Laura Roslin's administration and a well-known political figure within the fleet, was shown for the first and only time in the middle of the first season when the character was portrayed as being a natural choice for Roslin's vice president. The prominent politician has not been mentioned before or since.

• Buffy The Vampire Slayer: The character of Dawn Summers was added as a sister for Buffy in the first episode of Season 5. Although this was planned by the writers and explained later in the season, it was jarring to many viewers.

• The Cosby Show: In the pilot episode, an exasperated Clair Huxtable says to her husband "Why do we have four children?" He replies "Because we do not want to have five." However, in subsequent episodes, the Huxtables refer to having five children, with an oldest daughter away at Princeton. Sabrina Le Beauf made an appearance as Sondra Huxtable in a first-season episode, but was not listed on the opening credits until the second season. There was no explanation in the series for the addition of Sondra, though after the series ended Bill Cosby explained that the character of the eldest, collegiate daughter was added to provide a positive role model for black youth.

• Designing Women: Jan Hooks replaced Jean Smart at the beginning of the sixth season, playing Carlene Dobber, the sister to Smart's Charlene Frazier character. Despite several previous episodes giving details about Charlene's family, her sister Carlene was never mentioned.

• Doctor Who: The eighth season introduces the character Capt. Mike Yates, who we are informed has been a member of UNIT since at least the beginning of the previous season.

• The Dukes of Hazzard: Cousins Coy and Vance (see above) were never mentioned until they replaced Bo and Luke for a season, which might not seem that unusual until the viewer considers that the show's premise makes much of extended family ties.

• Frasier: The entire premise of this Cheers spin off introduced many concepts about the life of the Frasier character that were never alluded to in the original show, such as his mother's death, his surviving father, his brother, and his Seattle roots.

• Great Teacher Onizuka: Azusa's younger sister Makoto was never mentioned until she suddenly appeared in an episode because Azusa was kidnapped and detained by Teshigawara. Onizuka being too stupid to invest it himself, Makoto uses her very advanced detective skills to find her.

• Invader Zim: In the last episode of the series, "The Most Horrible X-Mas Ever", Zim is shown going about his business with a new sidekick: a purple, floating moose called "Minimoose". Minimoose is revealed to be robotic in origin and highly powerful, with a "Vortian Doomsday device hidden in his Nubs of Doom". Part way through the episode, a human being held captive by Zim notices Minimoose and asks "What is that?" to which Zim responds "Oh, uh, that's MiniMoose, my other sidekick, yeah. Yup, been with me the whole time!". Minimoose's origin episode had been written, but due to the show being cancelled by Nickelodeon was never produced. The X-Mas episode was originally scheduled to appear later in that series, after many of the unproduced episodes (including Minimoose's introduction), but the series was delayed, and the Christmas episode was shown at Christmas that year anyway - hence the disparity in the timeline, and (in true Zim style), making light of the unintended error rather than rewriting the whole episode without Minimoose.

• Mama's Family: Neighbor Iola Boylan did not appear until June 13, 1986, three years into the show's run. But according to the show she had lived next door to the Harpers her entire life -- flashbacks even showed her as a tiny girl playing in their kitchen -- but provided no explanation as to where she had been for the past three years. The fact that she seemed to be in the Harpers' house all the time made the situation even more unusual. One sees only 1% of a sitcom family's lives, so there will be many friends, neighbors, etc. who are unseen. However, Iola belongs to this category because her closeness to the family implies she would likely have figured into a number of scenes in the first three seasons, and her absence would be worthy of note.

• Matlock: For the 7th season, Ben's second daughter Leanne MacIntyre joined the cast, despite never being refered in the series before.

• The Muppet Show: Scooter the go-fer backstage and nephew of the theatre owner was seen as an only child however in the spinoff Muppet Babies he has a twin sister named Skeeter who was not in the previous series

• Prisoner: In 1984, six years into the run of this prison-based soap opera and with no original characters remaining amongst the prisoners, new characters Lou Kelly (Louise Siversen) and Alice Jenkins (Lois Collinder) were portrayed as having been in the cell block since the story events of the very first episodes from 1979. Siversen had played several bit parts in earlier years (though not as a prisoner) and had spent about a year as a cell block extra while Collinder had made a few brief appearances as a prisoner, but they had not been around nearly as long as the scripts later stated.

• The Simpsons: The 'Chuck Cunningham syndrome in reverse' was parodied by the Simpsons in the episode Itchy & Scratchy & Poochie. A new character, Poochie, was added to the Itchy & Scratchy show. Poochie was voiced by Homer Simpson. Poochie was near-universally despised, and was killed off in his second appearance. In the same episode, another new character, a young college-aged student named Roy, moves in with the Simpsons, and just as quickly moves out. Roy actually leaves with a sitcom premise. "Good news, everybody. I'm moving into my own apartment with two sexy ladies." This was typical of a Simpsons gag, and was not meant to affect the show's plot or non-existent timeline (the characters never age, the children are in the same grade each year, etc.).

• The Sopranos: In the fifth season, we meet Tony's cousin, whose name was actually Tony B (Steve Buscemi). Tony and he grew up together, thought of each other as brothers, used to pick on Christopher, etc. And even though we'd seen Tony go through his whole life in his therapist's office for five years, Tony B. was not mentioned until he joined the cast. This was acknowledged when Bobby Jr. asked Tony B. "How come I've never heard of you until now?" in the episode "Rat Pack"

• Space: 1999: In the second season mentioned above, Security Chief Tony Verdeschi (Tony Anholt) is a regular character, part of the command staff and treated by the other regulars as if he has always been. However, not only his character had never been seen before, but also no dialogue was written to even include a plausible explanation as to how he had somehow been promoted to that level. Alpha hadn't even had a security chief in the first season. By contrast, an entire episode was devoted to the introduction of Maya, the other new regular that season.
