Sandra Bernhard joins the Dixie Chicks (but only for one song)

Sandra Bernhard, don you now your gay apparel.

That's right, the holiday season is once again upon us. And you know what that means: advertisers helping you decide how to overdraw your checking accounts and max-out your credit cards! And there is none so powerful at taking your holiday money as Gap.

I am a big believer in the "Christmas is not your birthday" school of thought when it comes to the holidays, but every year these darn Gap commercials have me singing carols and taking eggnog to my neighbors and putting up a tree just so my cat can destroy it. This year, it's going to be worse. I even feel plastic reindeer coming on, because this year's Gap campaign is the best ever.

Not only do they have out comedian Sandra Bernhard, they've also got Jon Heder and Janelle Monáe walking through a "Winter Wonderland."

There's also Freddy Rodriguez, Romany Malco and Jason Biggs doing "We Three Kings" on bells, Flow Rida and Trey Songz doing "Jingle Bells," and my favorite, Rainn Wilson and Selma Blair singing my second favorite Christmas-ish song, "Baby, It's Cold Outside."

There's also a chorus of everyone singing "Jingle Bells" and it features Selma Blair rocking some stellar dance moves.

Watch all of the commercials here, and let us know which one's your favorite. Then hurry out to buy Gap stuff for all your friends and family. If you can resist the subliminal messages in the ads, you have uncommon willpower. I, for one, now own six Gap scarves.
