"Kidney Now!" is the season finale of 30 Rock. It will be a star studded showing with Sheryl Crow, Elvis Costello, Mary J. Blige, Clay Aitken, and I shutter to think of who else will be joining this motley crew of glorious stunt casting, but the storyline of Jack Donaghy finding out that his biological dad is Alan Alda (or Milton Greene), and he needs a kidney, should be pretty priceless. Hope Colleen shows up to settle the score.
There are exclusive sneak peak videos of 30 Rock's season finale over at SpoilerTV.com. Check it out.
