Mike's Watching:
 The Sing-Off (NBC, 8pm) It's like American Idol, but without the compelling personalities, and it's all a-capella! Compelling! Oh, did I say compelling? I meant boring. I'll still give it a chance.

River Monsters (DSC, 9pm) Killer catfish are hunted in the foothills of the Himalayas. Imagine how big that po'boy would be!

Whitney's Watching:
 How I Met Your Mother (CBS, 8pm) Harvey Firestein makes an appearance on my favorite CBS sitcom and is somehow involved in a storyline about Lily quitting smoking. Lily smokes?

Matt's Watching:
 Little People, Big World (TLC, 8pm) The Roloffs are an American institution.

Hoarders (A&E, 10pm) I'm watching this because I need inspiration to clean up my apartment.

Blakeley's Watching:
 I'll be watching White Christmas on DVD with a friend by a Christmas tree sipping egg nog in the Upper West Side.
