Not sure if Deen will be hawking hams the whole time, but y'all know she might. Reason to watch: NCCU marching band is part of the action.

Here's where we are: Val is pregnant with Ryan's (Morris Chestnut) alien baby, but she doesn't know she's having an alien's baby; V leader Anna can't figure out why Chad (Scott Wolf) hasn't followed up on that scary diagnosis they gave him; and FBI agent Erica Evans gets attacked in her home (while her son Tyler is still fraternizing with the enemy).

V (8pm, ABC) - Erica and her allies uncover a biological threat that may be linked to The Visitors. Meanwhile, Anna supervises the murder investigation of V while meeting with a special guest on the mother ship. I really like this show, but does anyone else find the teenage son supremely annoying? Also, this is the last episode till March 2010, so by that time we won't care about it anymore and the ratings can tank and ABC can go ahead and cancel it like they always do.

V (8pm, ABC) - ABC "re-imagines" NBC's 80s sci-fi drama about carnivorous reptilian aliens known as "The Visitors" who invade Earth.

Starring Elizabeth Mitchell (Juliet from "Lost"), Scott Wolf, and Morris Chestnut.

Biggest Loser (8pm, NBC) - The contestants are now competing individually. In tonight's episode, they all travel to Washington DC for a public workout at the Washington Monument, for a salad at the White House, and then a weigh-in on the steps of the Lincoln Memorial.
