For my money still the best comedy on television, "30 Rock" begins its fourth season tonight on NBC (9:30/8:30c). There are a few tidbits floating around AST about the new season, like upcoming guest star turns from Nate Corddry and Josh Fadem, and there's a fair amount of gossipy buzz surrounding Tracy Morgan's memoir, in which he slams former SNL cast-mates Chris Kattan and Cheri Oteri (don't miss the extra-saucy audiobook edition). As for the show itself, which picked up another Emmy for Best Comedy last month, the new season begins with Jack Donaghy ordering Liz Lemon to launch a nationwide talent search for a more relatable cast member (as Tracy Jordan and Jenna Maroney aren't connecting with everyday Americans).
