Kent Eanes/NBCNBC has taken Liz Lemon and made lemonade.
The network is playing the old switcheroo with its Thursday-night lineup, moving Tina Fey's 30 Rock to the post-Office 9:30 p.m. time slot and giving Scrubs the post-My Name Is Earl 8:30 p.m. slot.
Just three episodes of each series remain this season.
