60% Cotton / 40% Polyester - Full Knit Ugly Christmas Sweater Unisex Sizing - Adult Standard Fit Crew Neck If your state of mind has you traveling down the holiday road this season, and your favorite movie is National Lampoon's Christmas Vacation, then you'll love this super funny, geeky, pop-culture friendly, National Lampoon's Christmas Vacation Ugly Christmas sweater. Whether your favorite part of the movie is Chevy Chase going down the snow-covered hill on the space-age saucer slide screaming "Later, Dudes" or Cousin Eddie, or the squirrel in the tree that goes crazy, you can't discount the hilariousness of The Griswold's neighbors and all the hell that they go through next door as Chevy Chase tries to give his family the best Christmas ever. This "Why is the Carpet all Wet, Todd?" is a classic line from National Lampoon's Christmas Vacation spoken by Emmy-award winning actress Julia Louis-Dreyfus before she was cast as "Elaine" on Seinfeld -- it makes us feel as tipsy as Santa's elves on a crack cocaine bender.
