Plus, be sure to watch last night's episode below (from Hulu) or by clicking here, especially the monologue...he threw zingers at NBC left and right, and it was one of the funniest episodes I've seen in a while (which makes me even more sad that he might be finished with "Tonight" forever). There's also a great dig at NBC when Conan is interviewing Gary Oldman, so check out that part, too; Oldman's the first guest.
Tangentially related: watch Gary's impression of all four Beatles on Conan last night. Impressive and hilarious.
