fourth season of 30 rock

I can't wait until the fourth season of 30 Rock starts a week from Thursday. Here's a sneak peek/behind the scenes look, with the cast talking about a new plot, guest stars, and what it's like working on the set. I'm already laughing. (Note: it's a bit spoilerish; not necessarily the plots but some great lines you'll hear this season).
