Jon Hamm Guest Stars On The 'Simpsons' As Mafia-Hunting FBI Agent (VIDEO)

On Sunday night's "Simpsons," Springfield welcomed yet another celebrity guest voice in comedy-loving "Mad Men" star Jon Hamm. The episode focuses around Fat Tony, head of Springfield's infamous mafia, who Homer Simpson is forced to follow undercover by an FBI agent (Jon Hamm) trying to take down Tony from the inside.

Aside from obvious similarities to Jon Hamm's recent Ben Affleck picture "The Town" in which he plays an FBI agent, the episode is also chock-full of mobster movie parodies including "Goodfellas" and "Casino." Check out the clip below where Homer is coached by Hamm's character on going undercover before he enters prison in order to infiltrate Tony's gang.
