Last night, the cast of 30 Rock followed in Saturday Night Live's footsteps with a live show at the Upright Citizen’s Brigade, toeing the WGA picket line. Alec Baldwin, Tina Fey, Tracey Morgan, and, yes, Jack McBrayer staged their pre-announced performance in front of a small audience. "It wasn't as funny as it will be on TV," says one attendee of the already-taped episode they performed live, "but Baldwin was ridiculous as ever." Cookie jar collecting ridiculous, even.
