It's just not Christmas as a kid unless you get to snap a picture with jolly old Saint Nicholas -- whether you like it or not.
For many kids this is probably an awkward and terrifying experience -- you're ejected from the comfort of your parent's arms and you wind up in an bearded old man's lap who just so happens to be wearing an odd hat and a weird vest thing. His breath probably smells, but we can't confirm that detail for every Santa.
