FAMILY GUY and THE SIMPSONS 2014 ™ and © TCFFC ALL RIGHTS RESERVED. Fox Two of the most famous animated families in entertainment history are set to meet on Sept. 28, when the Griffins go on a road trip that makes an unexpected stop in Springfield. Peter and Homer bro out, Stewie and Bart cause trouble and even Bob from _Bob’s Burgers_ even makes a cameo in this self-aware crossover. ### Mad About You meets Seinfeld Crossover-happy _Mad About You_ (_Friends_ and _The Dick Van Dyke Show—_sort of, since the show was no longer on the air at the time—got their turns too) met _Seinfeld_ when viewers learned that Kramer was subletting Paul’s old apartment. ### Buffy the Vampire Slayer meets Angel Angel got his start on _Buffy_, so it was inevitable that the soulful vampire would encounter the slayer once the shows split. In 1999, after having a vision that Buffy was endangered, Angel made a return trip to Sunnydale—spurring her to follow him home. ### Homicide: Life on the Streets meets Law and Order _Homicide_ and _L&O_ worked together whenever a case involved both Baltimore and New York. As producer Dick Wolf confesses in this interview—the crossovers were “a pain in the ass” meant to annoy the network, but they worked. ### Full House meets Family Matters In one of several crossovers to take place in the family of ABC’s TGIF programming block, _Family Matters’_ Steve Urkel gives some much-needed advice to _Full House’_s Stephanie Tanner as she gets new glasses and deals with low self-confidence. ### Ally McBeal meets The Practice What does Ally’s law firm do when they need to consult with a lawyer with more homicide experience? Bring in the crew from _The Practice_, obviously. (The more interesting factoid about this episode: the two shows shared an executive producer but aired on different networks, [causing heartache](http://articles.chicagotribune.com/1998-04-27/features/9804270007%5F1%5Fdylan-mcdermott-crossover-lawyers "undefined") for the _The Practice_‘s ABC.) ### Cheers meets St. Elsewhere In 1985, the doctors from _St. Elsewhere_ visited the _Cheers_ bar. [According to the episode’s writer](http://kenlevine.blogspot.com/2008/03/st-elsewhere-goes-to-cheers-inside.html "undefined"), the medical show wanted to do a scene where the staff discussed their lives over drinks, and they pretty much figured ‘Why not at _that_bar?’ ### All My Children meets One Life to Live It’s difficult to know where to start with soap-opera crossovers…but it’s pretty hard to top a baby-swap. In this plot line, _One Life to Live_ and _All My Children_ families ended up with each others’ childr ### Everybody Loves Raymond meets King of Queens In the 1999 _King of Queens_ episode “Rayny Day” Ray Romano’s _Everybody Loves Raymond_ character stops by to play golf with Kevin James, his cross-sitcom buddy. (It wasn’t the first example of a crossover between the two CBS shows, and Ray Barone was also friends, in another crossover, with Fran from _The Nanny_.) ### The Flintstones meets The Jetsons In the 1987 TV movie _The Jetsons Meet the Flintstones_, two opposite ends of history collide when Elroy Jetson’s time machine transports his futuristic family back to the much-less-modern Stone Age. It wasn’t the only time the Flintstone family met some incongruous toons: a cartoon version of the _Bewitched_ crew briefly served as their next-door neighbors in 1965. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3430103/tv-crossovers-photos-simpsons-family-guy-episode/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3430103/tv-crossovers-photos-simpsons-family-guy-episode/"},"headline":"When Worlds Collide: 10 Classic TV Crossovers","datePublished":"2014-09-26T14:23:47.000Z","dateModified":"2026-05-11T05:07:40.523Z","description":"In honor of the Simpsons-Family Guy crossover episode, here are 10 iconic TV mash-ups","url":"https://time.com/3430103/tv-crossovers-photos-simpsons-family-guy-episode/","keywords":["Television","simpsons"],"thumbnailUrl":"","author":[{"@type":"Person","name":"TIME Staff","jobTitle":null,"url":"https://time.com/author/time-staff/"}],"articleSection":"Entertainment","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/entertainment/","name":"Entertainment"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/3430103/tv-crossovers-photos-simpsons-family-guy-episode/","name":"When Worlds Collide: 10 Classic TV Crossovers"}}]}] ```
