The Simpsons Guy
"The Simpsons Guy" is the one-hour-long premiere of thirteenth season of the American animated television series Family Guy, and the 232nd overall episode; it is a 44-minute-long crossover with The Simpsons, and was written by Patrick Meighan and directed by Peter Shin; it first premiered in the United States on Fox on September 28, 2014, where both The Simpsons and Family Guy have been aired since their respective first premieres in both 1989 and 1999, respectively.
In this episode, the Griffins meet the Simpsons at their house in Springfield, and decide to stay with them in Springfield directly after their car is stolen at the Springfield Gas Station at Springfield; after the Griffins get their car back, Peter is taken to court as a representative of the Pawtucket Patriot Ale brewery, his employer, when it is discovered that its ale is an unauthorized copy of Duff Beer.
The idea for a crossover episode was suggested by Family Guy executive producer and former The Simpsons writer Richard Appel, and the episode was announced by Fox in July 2013; five of the six main members of the voice cast of The Simpsons — with the exception of Harry Shearer — voiced their characters in the episode; "The Simpsons Guy" received mixed reviews from critics, who had differing opinions on how well the two shows combined.
