The Night Before the Night Before Christmas
You see, an elf causes some serious trouble on the night before the night before Christmas and Santa's sled leaves - with Santa - a day early. That by itself would be bad enough, but it doesn't actually end there. Yeah, the sled crashes, Santa gets amnesia, and it's up to some folks from Milwaukee, Wisconsin to get things back on track (which we assume takes more than just some coffee and a quick slap). Wow, the disaster that Christmas could turn into if these folks don't get Santa sorted out. Keep those fingers crossed.
