If you’re like me and love the Thursday night NBC comedy lineup, the switcheroo of time slots between “Scrubs” and “30 Rock” shouldn’t have too much impact. If, however, you’re devoted to only one of these shows, be aware that “Scrubs” will move to 8:30 PM and “30 Rock” will air at 9:30 PM.

Both “Scrubs” and “30 Rock” only have three new episodes left this season (boo!).
