In the course of the episode, the FBI agent has some frustration with Homer (natch), who is going undercover as a mobster, and “hilarity ensues.”
For Hamm, getting to voice a “Simpsons” character is a bit of a dream come true, since he’s been a fan since the early days of the show.
“I’ve been a fan from the very beginning … I have done the Bartman. I have all of the albums and many of the DVDs, so I’ve been a big fan for a long time,” says Hamm. “This is an amazing experience to be a part of … You don’t have to shave. I was considering not wearing pants. This is fantastic, I could do this again.”
Hamm’s episode of “The Simpsons” airs Sunday (Dec. 12) at 8 p.m. ET/PT on FOX.
