The actor will appear as Edward Scissorhands on the show in a brief cutaway gag.
“When [Johnny] was in the booth, he said that he felt like he hadn’t done that voice since he did it in front of the camera,” said Family Guy exec Mark Hentemann.
“He was able to snap right back into Edward Scissorhands once we pulled up a clip from the movie.
“He was amazing – and demonstrated extraordinary patience with all the fawning women in our office who swarmed him.”
