30 Rock is back!

NBC comedy is back with a new three-hour comedy block that kicks off at 8 pm. On 30 Rock, Tracy (Tracy Morgan) pays a visit to TV’s craziest and funniest medicine man, Dr. Spaceman (Chris Parnell). Plus the gang has to deal with potential budget cuts while Liz’s (Tina Fey) New Year’s resolution affects Jack’s (Alec Baldwin) wedding. 30 Rock brings the laughs at a new time, 10 pm.

Jenna (Jane Krakowski) gives Liz an earful when she has to share a dressing room.
