Here are this week’s SNL promos, featuring host Tina Fey with Kenan Thompson. What to expect this weekend? There sure has been a lot that happened in the three weeks the show’s been on hiatus. Osama! The royal wedding! The long-form birth certificate! Tornados! The Paul Reiser Show premiered and was cancelled! I’m sure “Sarah Palin” has an opinion on at least some of that stuff.
