Watch it

“Community” (8 p.m., NBC). This series is at its best when it gets surreal and absurd. Tonight’s special Christmas episode is all in claymation, so check and check. And check it out.

“30 Rock” (8:30 p.m., NBC). Liz and Avery try to convince Jack to let his mother in on a couple of secrets he’s been keeping from her. Like, I’m guessing . . . he’s married and will soon be a father.

“Fringe” (9 p.m., Fox). Looks like the war between universes is taking a break. Tonight it’s more a mystery-of-the-week about crazy stuff that happens after a guy gets his heart removed. Meanwhile, Peter re-evaluates his relationship with Olivia. Hmmm, yeah, there may be some issues there after he slept with her alternate self.

“It’s Always Sunny in Philadelphia” (10 p.m., FX). As Dee’s due date nears, the guys try to figure out who the baby-daddy is.

“The League” (10:30 and 11 p.m., FX). Tension is mounting as Christmas and the playoffs near. Then at 11 it’s the season finale as everyone tries to avoid “winning” the last-place Sacko trophy.

“The Colbert Report” (11:30 p.m., Comedy Central). Julie Taymor, director of the roundly mocked “Spider-Man” musical, is the guest. Oooh, too bad she’s not Conan’s guest — he’s been shredding it all week.

Record it

“Brew Masters” (8 p.m., Discovery). This is ridiculous — four episodes into the series, and it’s airing on its third different night. This, my friends, is how you kill a show’s viewership. Too bad, because it a really is an interesting series. Tonight, Sam works on a cedar brew and a big shipment of 120 Minute IPA draws red flags.

“The Office” (9 p.m., NBC). It’s an hourlong Christmas special, featuring the return of Michael’s old flame Holly (Amy Ryan), two office parties and a snowball duel between Jim and Dwight.

Giants vs. Braves, NLDS Game 1 (8 p.m., CSN-BA). Relive the Giants’ playoff run and watch Timmy Lincecum dominate the Braves. BTW, the play-by-play is by the Giants’ radio team, so you don’t have to listen to the TV pinheads we were stuck with in October.

“The Santa Incident” (8 p.m., Hallmark). OK, it’s a Hallmark movie so it’ll be sappy and awful, but the premise has Homeland Security shooting down Santa’s sleigh. And that sounds hilarious enough to check out, at least until it gets too schmaltzy to bear (so seven minutes or so). Ione Skye stars.

“Burn Notice” (10 p.m., USA). Sam tries to help a wrongly accused cop, while Michael tries to get the super-secret documents the team stole to the right people.

“Brad Meltzer’s Decoded” (10 p.m., History). A look at Thomas Jefferson’s secret codes.

“House Hunters International” (10:30 p.m., HGTV). After years of financial struggles, a San Francisco couple looks for an apartment in Reykjavik, Iceland. Um, I’ve been to Iceland, and I can tell them, it’s even more expensive there.

Skip it

“Barbara Walters Special” (9 p.m., ABC). In depth with Oprah. Because she just doesn’t get enough press.
