'30 Rock': Hamm and Winters and Sudeikis, oh my

Jon Hamm will return to "30 Rock" on Feb. 11, but Drew is not the only one of Liz Lemon's men making an appearance in the episode. Dennis (Dean Winters) and even Floyd (Jason Sudeikis) will be back as well.

So what are they doing dressed like dental hygienists?


That probably has something to do with Liz's (Tina Fey) plan to avoid Valentine's Day. Her brilliant plan? A root canal. We're guessing the anesthetic has something to do with these shots.


Elsewhere on Valentine's Day, Jack (Alec Baldwin) becomes taken with a CNBC host (Elizabeth Banks, beginning a multi-episode arc) and tries to romance her.


Plus, Bon Jovi!


The episode, called "Anna Howard Shaw Day," airs at 9:30 p.m. ET Thursday, Feb. 11.
