No surprise that Valentine's Day isn't all that great for Liz Lemon on '30 Rock' (Thurs., 9:30PM ET on NBC). She celebrates by having a root canal. But lo and behold, three of her former boyfriends show up in her hallucinatory anesthesia haze.

Oh well. Even if they weren't the real deal, at least we got our Jon Hamm fix, since 'Mad Men' won't be back until lord knows when (hopefully, July or August).
