The Simpsons-Family Guy Crossover at Comic Con 2014

For 25 seasons, The Simpsons have only ever participated in one official crossover episode (with The Critic.) But this fall, they'll meet up for the first (canonical) time with Family Guy's Griffins for their season premiere. 

 

Comic-Con attendees got an early taste of this long-awaited Simpsons-Family Guy crossover when a sneak preview of the episode aired during Saturday's Family Guy panel.
