What to Watch: December 24

'A Christmas Story' Marathon (8PM, TBS)
Yes, yes, Flick is still going to get his tongue stuck to the flagpole, Mr. Parker is still gonna get way too excited about the leg lamp and Ralphie's still gonna wish for that "official Red Ryder carbine-action 200-shot range model air rifle with a compass in the stock, and this thing which tells time." And, 'fess up, you're still going to catch at least one of two of the 12-consecutive airings TBS unspools in this 24-hour marathon of the holiday movie classic, which celebrated its 25th anniversary last year. Bonus fun: Check out the animated re-enacted of the movie - as performed by bunnies - at AngryAlien.com (http://www.angryalien.com/aa/xmas_storybuns.asp).'A Christmas Story' Marathon (8PM, TBS)

'Holiday Classics Marathon' – It's an all-day marathon full of Christmas classics, including Mickey Mouse, Winnie the Pooh and Pinocchio's Christmases, plus specials with Rudolph, Frosty and the Miser bros. (7AM, ABC Family)

'White Christmas' – If the 'Christmas Story' marathon doesn't ring your bell, perhaps the seventh consecutive airings of this 1954 Bing Crosby/Rosemary Clooney gem will (9AM, AMC)

'It's a Wonderful Life' – "Teacher says, every time a bell rings, an angel gets his wings" (8PM, NBC)

'Tarantulas and Their Venomous Relations' – Including the rarest spider in the world, a one-of-a-kind creepy-crawly in Ecuador. Sorry PETA, but we'd still squish it if it crossed our path (8PM, Science Channel)

'Raising the Bar' – The Mark-Paul Gosselaar legal drama didn't get renewed, but at least the network sends it off with a three-hour marathon (10PM, TNT) series finale
