Everyone knows the holidays cause enough stress to make even a smooth flowing Christmas Vacation enough to drive you crazy, but when you've had to put up with your parents, your in-laws, your red neck cousin-in-law all while finding out that your company didn't give Christmas bonuses after you've already spent it you just might flip out like Clark Griswold did. This Christmas Vacation t-shirt shows Clark's rant of "When Santa squeezes his fat white ass down that chimney tonight, he's gonna find the jolliest bunch of assholes this side of the nuthouse" underneath a picture of the Family truckster with the root ball and Christmas tree strung to the top.
