What happens when TV icons Don Draper and Homer Simpson meet? We're about to find out.

The Simpsons producer Al jeans confirms to Entertainment Weekly that Jon Hamm will voice a character on this animated hit. He says:

"Jon’s a gruff FBI man. Homer asks if he can pick his undercover name and finally Jon just says, ‘Your name will be Nicky Blue Pants Altosaxophony.’ Homer says, ‘Do I get to keep the name when I’m done with it?’ and Jon says, ‘No, it’s the property of the government.’  He has no patience for Homer.” 

The episode will air in December.

Hamm, of course, has proven his comedic chops with a couple stints on 30 Rock. He returns as Don Draper this Sunday on the Mad Men season four premiere.
