The Sing-Off (NBC) — Contestants from throughout “The Sing-Off”‘s three seasons return to croon their favorite holiday songs. Flo Rida guest stars to sing “Give the Jew Girl Toys.” Probably. (Thank you to Nadia for the merriment-addition above.)
American Country Awards (FOX) — With performances from Toby Keith, Hip Diddler, Blake Shelton, Trace Adkins, Butterball Jackson, Thompson Square, and special guest, the Big Shirtless Rod Experience.
Prep & Landing: Naughty vs. Nice (ABC) – The first special, which aired in 2009, was entertaining, and this one has a lot of people you like in it, such as Dave Foley, Sarah Chalke, Rob Riggle, and Chris Parnell. There are worse ways to spend a December Monday night, like watching “2 Broke Girls.”

Long Island Serial Killer (A&E) – Do uncaught serial killers watch specials and films about their work? Like, did the Zodiac Killer go to an 11 a.m. matinee screening of Zodiac at his local Regal movie theater, and loudly harrumph at everything Fincher got wrong, and will the LISK keep this A&E special on his DVR for months? These questions need answering – after they catch the guys, of course.
