"30 Rock" has quickly earned a reputation as a show that is totally unafraid of the celebrity cameo: Jerry Seinfeld, Jon Bon Jovi, and even Oprah have walked the hallowed halls of a studio set that looks like 30 Rockefeller Center. Now, Aaron Sorkin, the screenwriter most recently of The Social Network is joining the "30 Rock" Celebrity Cameo Club, with his episode set to be shown on NBC in March or April. Not much in the way of details, although I would guess there's going to be a lot of jokes about the "Sorkin style" (walk and talks, and all that) on his various TV shows over the years, and also about the similarities between "30 Rock" and Sorkin's "Studio 60 On the Sunset Strip." Or maybe a scene in which Tracy Morgan shouts "you can't handle the truth!" (via The Wrap)
