This image is so old I had it on my mp3 player, when I was a kid. (Don't ask why, we'll both just cringe) He just has very thick legs, so he can do all the cool parkouring, I imagined him doing, while sitting in the backseat of my parents car, listening to Nightwish and Subway To Sally.

…man, this post is bringing back some memories.
