Christmas is the easiest holiday to make fun of because it can be so hokey and jolly. It's like the office jolly holly -- someone who's always smiling, always bringing gooey sweet goodies to the office for no reason, always cackling at everyone's jokes, no matter how bad they are or what MadTV episode they were taken from.

But deep down, you know that anyone that happy has to be making up for something equivalently dark and sinister. They are hiding a dark secret, something they can't even admit to themselves. You just know that the rises in sick leave usage after she brings her secret recipe brownies aren't coincidences.

Christmas wears the same mask. All it takes is a little scratching to find something dark and funny behind its red and white veneer. SNL has had some great success taking pot shots at Christmas, even during the down times, for this very reason. It's hard not to find something funny about Christmas, but it's hard to keep finding something funny about it long after the turkey has been picked clean and the eggnog has left a thin layer of plaque on the inside of your small intestine. Here are the best of the best.

'A Christmas Story'
(8PM, TBS) 24-hour marathon
You know the drill by now -- every year since 2004, TBS has run this beloved holiday flick for 24 hours straight.

That means you have 12 chances to see Flick get his tongue stuck to the flagpole, Ralphie's dad to get excited about the leg lamp and, of course, Ralphie wish for a "an official Red Ryder carbine-action 200-shot range model air rifle with a compass in the stock, and this thing which tells time."

The movie, which celebrates its 25th anniversary this year, has inspired everything from the TV show 'The Wonder Years' and the production of real leg lamps (seriously) to a 'Mythbusters' episode (which airs on Dec. 25 at 9AM on Discovery) and even 'A Christmas Story' Museum.
