The Griffin family is leaving Quahog, Rhode Island and heading to Springfield to pay a visit to Homer Simpson and his brood for a special crossover episode between Family Guy and The Simpsons.

The episode, which will air in 2014 as a part of Family Guy‘s upcoming season 12, will be titled “The Simpsons Guy” and will feature longtime Simpsons cast members like Hank Azaria, Nancy Cartwright, Julie Kavner, and Yeardley Smith on the show for the first time. Dan Castellaneta will also appear in the crossover episode, making his second “Homer” appearance on Family Guy following a brief cameo in 2012.

Castellaneta’s one-shot was hardly the only time Simpsons’ characters have been seen on Family Guy, and there have also been subtle and not-so-subtle mentions on The Simpsons regarding their junior competitor (Plagiarisimo, anyone?). But this most recent announcement represents something a bit more significant.

Here’s a synopsis for the episode:

In “The Simpsons Guy” episode of ‘Family Guy,’ Peter (Seth MacFarlane) and the Griffins get out of dodge and end up in Springfield, where they are greeted by a friendly stranger named Homer Simpson (guest voice Dan Castellaneta), who welcomes his new “albino” friends with open arms.

The families get along famously: Stewie (MacFarlane) becomes obsessed with Bart (guest voice Nancy Cartwright) and his old-fashioned pranks; Lisa (guest voice Yeardley Smith) takes Meg (Mila Kunis) under her wing and is determined to find something – anything – at which she excels; Marge (guest voice Julie Kavner) and Lois (Alex Borstein) ditch housework for a little bonding; and Peter and Homer fight over the best beer in town – Pawtucket vs Duff.

As of right now, there’s no word on whether or not “The Simpsons Guy” will merely feature Simpsons characters or if any members of The Simpsons‘ writing staff had a hand in the architecture of this episode – an episode that seems like little more than an excuse to get all of these beloved characters on the same screen for the first time (sort of like, say, The Jetsons Meet the Flintstones).

Perhaps The Simpsons‘ creator Matt Groening and Family Guy creator Seth MacFarlane can convince us that the crossover is more than just a stunt at The Simpsons/Family Guy panels at Comic-Con 2013 this Saturday. Stay tuned as this story develops.

What do you think, Screen Rant readers? Will you be watching this crossover episode when it airs in 2014? Let us know in the comments.

Both The Simpsons and Family Guy will return to FOX’s Sunday night schedule fall 2013.
