Oh this is an easy one: CHRISTMAS VACATION!
"Hey! If any of you are looking for any last-minute gift ideas for me, I have one. I'd like Frank Shirley, my boss, right here tonight. I want him brought from his happy holiday slumber over there on Melody Lane with all the other rich people and I want him brought right here, with a big ribbon on his head, and I want to look him straight in the eye and I want to tell him what a cheap, lying, no-good, rotten, four-flushing, low-life, snake-licking, dirt-eating, inbred, overstuffed, ignorant, blood-sucking, dog-kissing, brainless, dickless, hopeless, heartless, fat-ass, bug-eyed, stiff-legged, spotty-lipped, worm-headed sack of monkey shit he is! Hallelujah! Holy shit! Where's the Tylenol?"
Love love love this movie so much! I watch it at least 5 or 6 times every holiday season, but I think last year I may have reached 12 times? Yeah, I love it that much.
I also love Home Alone 1 and 2 and will never outgrow them, but Christmas Vacation will forever be Number 1 in my heart!
