Santa Claus has to visit a lot of houses in very little time. When the reindeers are on break (Rudolph really likes his "egg nog", Santa sometimes needs to do a little traveling on his own. In a city or crowded neighborhood parkour can actually be pretty useful and obviously pretty bad ass.
If I saw Santa Claus backflipping out of my window I think I would have a lot more respect for the guy. I mean coming down a chimney and eating cookies sounds great, but where is the action and excitement. Parkour Santa is a true champion of awesomeness.
If you like Santa's moves try this move on for size.
