Yesterday, we learned Dennis Duffy was returning to 30 Rock for an episode entitled “Mazel Tov, Dummies!” So, unless Tracy was actually going to have that werewolf bar mitzvah of his, we knew something was up. NBC announced today that Liz Lemon will be marrying Criss Chross on the November 29 episode. We can only imagine the buffet table they’ll have.
