The Biggest Loser: Couples (8pm, NBC) - Another local couple hits the tube tonight on Biggest Loser.
Homeland Security: USA (8pm, ABC) - A new reality series that tracks Homeland Security cops as they patrol the US borders.
Scrubs (9pm, 9:30, ABC) - Scrubs makes the jump from NBC to ABC tonight. Will it be the same?
Nip/Tuck (10pm, FX) - The second half of Nip/Tuck's fifth season starts tonight. In the previous show's cliffhanger, Sean was stabbed by Sharon Gless and he is now in a wheelchair. Also on tap for tonight, Christian gets a troubling medical diagnosis. But don't think these guys let paralysis and life-threatening disease get them down. They still find time to woo the ladies. Tonight's episode definitely earns its TV-MA rating. The V, the S, and the L -- all the letters in the alphabet, pretty much.
Also new tonight -- Law & Order:SVU, The Mentalist, Fringe, NCIS, Without a Trace, and 90210.
