Effective this week, Scrubs and 30 Rock are switching places on NBC's Thursday-night lineup to close out the season. Each series has three new episodes yet to air.

Scrubs moves to 8:30 pm/ET (following My Name Is Earl) while Liz Lemon and the gang at 30 Rock go to 9:30 pm/ET (after The Office). - J.R. Whalen
