Better put a new battery in the clicker: The January frenzy is upon us as the networks play midseason schedule bingo, moving current shows to new time slots, introducing a slew of new series and bringing back old favorites for fresh fun.

Jenna Elfman, Tom Cavanaugh ("Ed"), Fred Savage, and Jane Curtin are among those debuting in new series this month. The twin Fox heavyweights "American Idol" and "24" swing back into action in January as well.

In a risky effort to kick-start its once dominant Thursday lineup, NBC moves red-hot, first-year comedy "My Name is Earl" from Tuesdays to 8 p.m. Thursdays, starting tonight.

The cheerful screwball tales of lottery winner Earl Hickey seeking good-karma redemption must now do battle with CBS' fearsome "CSI: Crime Scene Investigation," TV's No. 1 show. Oooh, scary.

Meanwhile, let's check in on other midseason eye candy:
