"Finally I can get my hands on this guy!," said Homer Simpson (voiced by veteran voice actor Dan Castellaneta) in a statement released by FOX in reference to meeting Griffin in the future episode.

Peter Griffin also made comment about the landmark episode that will air on the FOX network in a few months.

Stewie Griffin will marvel at Bart Simpson's devious hijinks when the two troublemakers meet each other and cause mischief in the streets of Springfield.
