It's December, which - of course - makes it the most wonderful time of the year for those who like watching holiday specials of their regular shows and seeing favorite character act merry and bright. Here are some highlights amongst the blizzards of seasonal programming over the next month.

NTSF:SD:SUV: Christmas Activity

Adult Swim's parody of every over-the-top procedural on network television gets to tick another cliche off its list with this Very Special Holiday Episode, in which the team is attacked in the middle of its Christmas party by "the evil Alaskan Santa Claus." Paul Scheer, I'm counting on you for at least one reference to Yukon Cornelius, dammit. (December 6 at 12:15pm Eastern on Cartoon Network)

12 Disasters of Christmas

What better way to celebrate not only the holiday season, but also the rumored end of the world than with a Syfy Original Movie based on Mayan predictions of the Apocalypse that sees a new disaster every day, leading up to the end of everything we know… or, perhaps, the arrival of Ol' Saint Nick.( December 8 at 9pm Eastern on Syfy)

Robot Chicken's ATM Christmas Special

The seemingly unstoppable Robot Chicken returns with another holiday special, this year promising the yuletide cheer of Kano from Mortal Kombat and something that it's describing as "the writers give GI Joe a very special Christmas." That last one alone guarantees that I'll tune in far more than the promise of a Justin Beiber sketch. Aren't we all over Biebermania by now…? (December 9 at 12pm Eastern on Cartoon Network)

Syfy 20th Anniversary Special

A trip down memory lane for Syfy as it celebrates two decades of existence with a two-hour special that looks back on the highs and lows of the channel's output so far. Expect a lot of Battlestar Galactica and Stargate talk, as well as the potential comedy of seeing whether or not the outrage over renaming itself from "SciFi" to "Syfy" gets mentioned at all.

Doctor Who

Now this hour may not be the most wonderful time of the year, but it's very likely to be the most wonderful time of the month: The Doctor returns, depressed as Scroogelike, and only Clara/Oswin can save him from the darkness in his own soul… which is good, because only he can save the world from killer Snowmen. Yes, killer Snowmen. Admit it: This will be amazing. (December 25 at 9pm Eastern on BBC America)
