“Mad Men” star “John Hamm” has joined the cast of “30 Rock” for AT LEAST 3 episodes this season. “I just finished a couple of episodes, and I’ll go back in the new year and do another one of those, and then we’ll see what happens,” Hamm said Tuesday at a benefit for the UCLA School of Theater, Film and Television according to the wire service.

Hamm is playing a love interest for series star Tina Fey, and after his spectacular performance on SNL earlier this year, I can’t wait to see how he fits into the insanity that is “30 Rock”.
