A Two-Minute Preview Of Thursday’s Season Finale Of 30 Rock

Today NBC put up several scenes from Thursday’s star-studded (Mary J. Blige, Elvis Costello, Clay Aiken, and Alan Alda again) season finale of 30 Rock. I supposed it contains “spoilers” if jokes count as spoilers (“The colon pushes out the–“):

Clay Aiken and Kenneth Parcell are cousins! That twist sort of wrote itself when Clay’s manager called Tina Fey, but it’s 30 Rock, so it’s fine.
