Following years of so-called “rivalry” between the two shows, Family Guy and The Simpsons are set to do an all-out crossover with each other, EW is reporting. In an upcoming Family Guy episode–called The Simpsons Guy–the Griffins somehow wind up in Springfield, where “Stewie is impressed with Bart and his assortment of pranks, Lisa tries to figure out exactly what it is that she’s good at, and Marge and Lois do some bonding. Meanwhile, Peter and Homer argue over which beer is better: Pawtucket or Duff.” All major voice cast members of The Simpsons are set to guest star in the episode, which is set to air in late 2014. Unfortunately for fans, a crossover between Family Guy and American Dad–which has been rumored for years–, is now almost certainly never going to happen, since American Dad is is moving from FOX to TBS after the show’s next season has aired.
