How much do you know about Christmas – about its origins and its many beloved traditions? Do you know where the idea of stocking-stuffers comes from? Or how lights found their way onto the Christmas tree? Or why we all have the jolly, red-suited, white-haired image of Santa Claus in our heads?

• “This is a full-blown, four-alarm holiday emergency here. We’re gonna press on, and we’re gonna have the hap, hap, happiest Christmas since Bing Crosby tap-danced with Danny fucking Kaye. And 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.” — Clark W. Griswold Jr.
