30 Rock Season Finale Preview!

There's nothing like a sneak peek of tomorrow's 30 Rock finale to get us through humpday! Excited about the celebrity guest trifecta of Elvis Costello, Mary J. Blige and Clay Aiken! Not to mention the return of Alan Alda's character, as Jack Donaghy's long lost biological Bennington professor father ("Bennington! How's that going? Teaching all those kids who couldn't get into Middlebury?") in need of a kidney transplant. Was it just us, or does his relationship with Jack (liberal dad, conservative son) slightly remind you of his relationship with Lukas Haas in Everyone Says I Love You? It's a little farfetched, yes, but we always jump at any excuse to talk about Lukas Haas!
