That Santa Claus sure is a mysterious fellow. His intentions are good -- the guy laps around the world every year to give kids presents, after all. But what's really going on inside that jolly, fur-clad head of his?
We tracked down a few vintage Kris Kringle cards that appear to illustrate some of Santa's bad habits. They're most likely innocent, but really, we wouldn't be doing our job if we didn't at least share them.
Take a ho-ho-ho through the gallery above. What do you think? Any funny ones we missed? Give us your own captions for the photos below.
