5 Most Infamous ‘Jump The Shark’ Sitcom Moments in TV History

To say a TV show jumped the shark is to say it made such a poor story choice that viewers realized its best days were firmly behind it. Almost every show has its golden age, and the jumping-the-shark moment often clearly marks the end.

The phrase comes from a 1977 episode of “Happy Days” in which Fonz (Henry Winkler) literally jumps over a shark on water skis. The absurdity of the moment, combined with the unconvincing editing, served as a clear dividing line for many viewers. This is when the emotional, earthy tone of the show’s early days completely gave way to the cartoonish antics of later seasons.

The key to a true jumping the shark moment is that it has to tie into a complaint fans already had about the show. For example, many “Happy Days” fans were already annoyed that flagship character Fonzie was slowly taking over the show. These complaints would still exist even if the shark jumping scene never happened, but the scene perfectly summed up everything that was wrong about the direction the show was taking. The five shows included in this list don’t involve literal shark jumping, of course, but they all have an infamous moment that confirmed their fans’ worst fears about where things would go.

Toward the end of the fifth and final season of “The Brady Bunch,” the show suddenly introduced 8-year-old cousin Oliver (Robbie Rist) to the cast. Not only did fans find Oliver annoying, but the fact that he had never been mentioned before made his presence even more forced. It was hard not to view Oliver as a desperate Hail Mary on the part of the writers.

Susan Olsen, who played his youngest daughter, Cindy, on the show, told fans during a panel in 2025 (via People) that Oliver was the show’s “shark jump” moment. She added: “Every time a show starts to drop a little bit in the ratings, they start adding the cute kid.” Christopher Knight, who played younger brother Peter Brady, agreed with Olsen. He told fans: “I was looking for the exit when we saw Oliver walk through the front door.”

Although the series was already becoming a bit stale before Oliver appeared, the awkwardness of his sudden inclusion tends to place the weight of the series’ ending on him. Maybe it’s unfair, but the jump-the-shark moments are often quite symbolic. For his part, Robbie Rist has since acknowledged the backlash, telling Cracked in 2023: “People were coming up to me and saying, ‘You’re the guy who killed’ The Brady Bunch..’ This was consolidated in the early days of the Internet. »

The first five seasons of “Laverne & Shirley” were set in Milwaukee, Wisconsin, and — for a time — the show had a down-to-earth, working-class charm that fans loved. But, after a series of storylines in the Season 6 premiere, most of the main characters suddenly moved to Burbank, California. Suddenly the show became a lot sillier and less relatable to fans.

The move to California was followed by a number of other problems that killed the series: Cindy Williams, who played the titular Shirley, left the series after season 7 on bad terms with the show’s producers. Michael McKean (who played Lenny) also had his role reduced in the final season, making the show feel strangely empty.

Some fans consider the major cast departures to be the real jumping-the-shark moment, but the sudden move west was the real turning point. This came across as a desperate attempt to freshen up the series, but it only served to remind viewers that the series was running on fumes.

The bizarre fantasy sitcom “I Dream of Jeannie,” arguably one of the best TV shows of the ’60s, centers on a genius named Jeannie (Barbara Eden) and an astronaut named Tony (Larry Hagman) and their will-they-won’t-they dynamic. However, after five seasons of charming romantic tension, NBC executives forced the two characters to marry.

“I was very upset — even though no one would listen to me,” Barbara Eden told Forbes in 2025. Series creator Sidney Sheldon was also dismissive of this plot point, telling the Television Academy that it was what “ultimately killed it.” He recalled that ABC head Mort Werner gave him an ultimatum at the end of the fourth season: if he wanted the series renewed for season 5, he would have to marry Jeannie and Tony.

“I tried to make the storyline as interesting as possible, but with their marriage, the relationship changed and much of the fun disappeared from the show,” Sheldon wrote in his 2006 memoir. “At the end of the fifth year, ‘I Dream of Jeannie’ was canceled. Mort Werner had taken a hit series and destroyed it.”

Although “Family Matters” started out as a blue-collar version of “The Cosby Show,” the twelfth episode introduced Steve Urkel (Jaleel White) — and everything in between. Really escalated from there. By season 2, Urkel had become a main character, and by season 3, he had essentially taken over the series. None of this was necessarily a bad thing — America loved Urkel, after all — but in Season 5, Urkel began introducing sci-fi elements into the show on a regular basis.

In “Dr. Urkel and Mr. Cool”, Urkel develops a chemical formula that transforms him into a cool, talkative guy named Stefan. That’s fine for a one-off episode, but in the Season 5 finale, “Stefan Returns,” Urkel invents a transformation chamber that allows Stefan to return regularly. The Transformation Chamber is where the show officially becomes too wacky for its own good.

The Transformation Chamber also helped solidify “Family Matters” as one of the most notorious examples of a show that took a shocking departure from its original premise. Famously, it even inspired a “Key & Peele” sketch in which Carl Winslow actor Reginald VelJohnson (played by Jordan Peele) speaks to the writers about the last episode’s ridiculous premise. “Steve Urkel turns Carl into a giant sandwich and accidentally eats him?” he said incredulously. Compared to some of the real-life detours Urkel takes later in the season, this premise isn’t even that far-fetched.

Much of the appeal of “Roseanne” came from how relatable its working-class main characters were, which is why it seemed such a puzzling choice for them to win the lottery in the second episode of the ninth season. With the sudden influx of $108 million for the characters, the series turns into an escapist fantasy sitcom, and much of its charm is instantly lost. The only halfway respectable explanation for this plot deviation is that the writers were out of ideas.

The show’s ratings declined soon after, and critics were quick to speculate that the lottery storyline was the main reason. Roseanne Barr defended the final season as it unfolded, telling the AP: “My senior year is the year I’m going to give everyone’s characters their dreams.” However, that didn’t turn out to be true: the series finale reveals that the lottery win — along with many other major plot points from Season 9 — were just part of a book that Roseanne Conner is writing about her life.

Critics found the finale so confusing that they thought the big twist must have been some sort of apology to fans frustrated by the lottery storyline, but a spokesperson for the series’ production company told the Philadelphia Daily News that it had been planned in advance. While the latest episode has joined the TVLine list…
