I recall, a few years back, when LBT was a nominee for a feature on Thanksgiving, only to be defeated by An American Tail! That's a good movie, but still, LBT has more significance during that time of year <_<.
My favorite holiday movies are A Christmas Story ("You'll shoot your eye out!"

), Home Alone, Home Alone II: Lost in New York ("Merry Christmas, you filthy animal!"

), How the Grinch Stole Christmas (Jim Carrey version), A Christmas Carol, and Rudolph the Red-nosed Reindeer.
