Beauty and the Geek

Beauty and the Geek: Dr. Drew Pinsky, who will apparently appear in anything, shows up as the geeks join him on his Loveline radio program. And Matt, the poet from Dallas, battles back from the injury he suffered in last week's football game. 7 p.m., KDAF/Channel 33

The Biggest Loser: Not cowering at all in the face of American Idol, The Biggest Loser does its weekly two-hour edition, with all the eliminated contestants returning -- but only one team allowed back in the game. 7 p.m., KXAS/Channel 5

Aside from a handful of new things, including the season finale of Beauty and the Geek, most of tonight's offerings are specials or repeats. The best of the lot is both, a rerun of a Christmas special that hasn't aged, even though it's more than 40 years old.
