Fox has announced that The Simpsons will be meeting the Griffins in a crossover episode of Family Guy next year.
The episode, titled "The Simpsons Guy", will see the Griffins take a roadtrip and end up in Springfield and is scheduled to be broadcast in the US next autumn.
Voice actors from The Simpsons confirmed for the crossover include Dan Castellaneta, Julie Kavner, Nancy Cartwright, Yeardley Smith and Hank Azaria.
The episode will see the families bond, as Stewie and Bart compare pranks, while Lisa dedicates all her time trying to prove that Meg must be talented at something...yeah, good luck with that one.
In terms of the parents, Marge and Lois will escape the house after discovering they have a lot in common, while Peter and Homer prepare try to answer the most important question they can think of: which beer is better, Quahog's Pawtucket or Springfield's Duff?
The two series have a chequered history, with the rivalry between them initially being fairly hostile. In recent years, however, this has mellowed, with Family Guy creator Seth McFarlane even lending his voicing to The Simpson's 24th series finale.
Look forward to seeing this episode lol!
