Looks like all those Second City improv classes finally paid off! The cast of '30 Rock' stopped by 'Late Night with Jimmy Fallon' to promote, and perhaps warm-up for, their Thursday night live episode.

Tina Fey proved to be the MVP on a team with Alec Baldwin and Jack McBrayer while Fallon paired up with Jane Krakowski and Tracy Morgan. Fey had no problem with an LMFAO song while a Def Leppard classic proved too tough for Team Fallon, despite Tracy Morgan's history with strip clubs.

To be fair, Tina Fey is an old hand at 'Late Night' charades. She played the classic game with "Weekend Update" co-anchors, Amy Poehler and Seth Meyers once before during Fallon's late night shift.  Needless to say, she rocked "The DaVinci Code."

Check out Tina Fey and the rest of the '30 Rock' cast battling it out in the two clips below!
