30 Rock has just three weeks left before it ends its run, and Jimmy Fallon had the core cast - Tina Fey, Alec Baldwin, Tracy Morgan, Jane Krakowski, and Jack McBrayer - on his show last night to discuss the show and to say goodbye. Fallon ditched his desk to just sit around with the gang and chat like Oprah, and you can watch the rest of the show after the jump, which also includes Tracy Morgan covering a Boyz II Men song.
