Summary

Sitcom crossovers are an odd TV tradition, bringing together characters from unrelated shows for new and unique stories. If they are executed poorly, crossover episodes can add up to little more than cheap marketing exercises for their shows, but there have been plenty of sitcom crossovers that have struck upon a winning formula. Often, the key is to create a story which brings the best out of both sets of characters.

Crossover episodes are often among the most highly anticipated episodes of any show, but they don’t always live up to these expectations. Not all shows can blend their styles of humor so easily, and the fact that they are on the same network isn’t a good enough reason to attempt to combine them. Sometimes, sharing a creator or an actor can help things run smoothly, and many of the best sitcom crossovers benefit from more connections between the two shows.

7Full House Season 4, Episode 16, “Stephanie Gets Framed”

Full House & Family Matters

Family MattersandFull Houseboth represent a bygone era of family-friendly sitcoms which always paired humor with a sweet moral lesson. TheFull Houseepisode “Stephanie Gets Framed” has exactly the kind of earnest attitude that would be ripped to shreds by the modern era’s more cynical worldview, but it’s still nice to see Jaleel White’s Steve Urkel comforting Stephanie when she gets nervous about wearing glasses.

Family MattersandFull Houseboth represent a bygone era of family-friendly sitcoms which always paired humor with a sweet moral lesson.

Steve Urkel’s cameo inFull Househelped fill the gaps in the theorized “TGIF universe,” which accounts for crossovers between multiple ABC shows which aired on the same night in the 1990s.Sitcom crossovers were more common back then than they are now, and not just on ABC. “Stephanie Gets Framed” works well because it simply lets Steve Urkel unleash his chaotic comedy on a new environment, and the Tanner family don’t quite know how to handle him.

6The Jetsons Meet The Flintstones

The Jetsons & The Flintstones

The Flintstoneswas one ofHanna-Barbera’s biggest hits, and its success has led many to seeThe Jetsonsas little more than an attempt at recycling the same concept. Both shows feature recognizable families living in wildly different time periods. The Flintstones may use dinosaurs as home appliances, while the Jetsons have a robotic maid, but both families face the same timeless problems.

The Flintstones may use dinosaurs as home appliances, while the Jetsons have a robotic maid, but both families face the same timeless problems.

Hanna-Barbera’s two iconic families crossed paths in the TV movieThe Jetsons Meet the Flintstones,after a time machine mishap sends the Jetsons tumbling all the way back to Bedrock. Before George can repair the machine, Fred Flintstone and Barney Rubble accidentally send themselves thousands of years into the future. This creates two fish-out-of-water stories at once, which further drives home the point that human foibles and family strife will remain the same forever.

5Friends Season 1, Episode 16, “The One With The Two Parts, Part I”

During the first few seasons ofFriends,as the show was exploding in popularity, Lisa Kudrow was also in Mad About You. The writers ofFriendscame up with the brilliant idea of making Kudrow’s two characters identical twins. Ursula, the testy waitress fromMad About You,became Ursula Buffay, and she pops up in multipleFriendsepisodes over the years. Her first episode also features brief cameos from Jamie and Fran.

The episode delivers a great meta joke about Lisa Kudrow’s role in both shows, and it’s a strong outing regardless of its ties toMad About You.

“The One With Two Parts” isn’t a full crossover episode, since it doesn’t feature most of the main cast fromMad About You.However, it’s a great meta joke about Lisa Kudrow’s role in both shows, and a good episode regardless of its ties toMad About You.Ursula developed a lot more after this first appearance, quickly becoming one of thebest side characters inFriends.

4New Girl Season 6, Episode 4, “Homecoming”

New Girl & Brooklyn Nine-Nine

The two-part crossover starts with aBrooklyn Nine-Nineepisode, in which Jake has to commandeer a car being driven by Jess. She is less than amenable to the idea, but this minor interaction is merely the set-up for theNew Girlepisode which follows.

Nick and Winston have a great B-story trying to scrape together enough money for subway fare by being street performers who never perform, and they run intoBrooklyn Nine-Nine’s Charles Boyle.

“Homecoming” features the most interactions betweenNew Girlcharacters and the gang at the 99th precinct.It perfectly captures the clash of cultures between the East and West coasts, as Jess' quirky charm is bulldozed by the businesslike New Yorkers. Elsewhere, Nick and Winston have a great B-story trying to scrape together enough money for subway fare by being street performers who never perform, and they run intoBrooklyn Nine-Nine’s Charles Boyle.

When he ruthlessly dispatches a team of assassins, he realizes that he may have some stuff to figure out. Archer only thinks he is Bob because he has entered a fugue state and lost his memory after a traumatic incident.

The juxtaposition between the cutesy charm ofBob’s Burgersand the bloody violence ofArcherproduces plenty of hilarious moments.

Linda, Gene and Louise only appear in the first few minutes of “Fugues and Riffs,” but their presence is felt throughout the whole episode.H. Jon Benjamin essentially plays Bob Belcher being thrown into an episode ofArcher,as the mild-mannered restaurateur has to get to grips with an assassination plot. This juxtaposition between the cutesy charm ofBob’s Burgersand the bloody violence ofArcherproduces plenty of hilarious moments. Benjamin’s deadpan voice is perfect for the humor.

2Family Guy Season 13, Episode 1, “The Simpsons Guy”

Family Guy & The Simpsons

Family Guyhas often laughed at its perceived similarities toThe Simpsons,but the crossover episode between the shows highlights just how different they are.

1The Simpsons Season 6, Episode 18, “A Star Is Burns”

The Simpsons & The Critic

The Simpsonshas had other crossover episodes throughout its 35-year-long run, including aFuturamacrossover in season 26, but “A Star Is Burns” is by far the greatest.
