If you don't know about Parkour, often referred to as Free Running, it's the hip, urban thing to do when you want to jump off of things. Buildings, stairwells, parking decks — there is nothing these crazy kids won't jump off of! It's been popularized in commercials for Reebok, Madonna videos, and now, properly I might add, with Super Mario Bros. music and sound effects.

There's something quite satisfying about accomplishing a twenty foot drop, then shaking hands with spectators to bonus chimes.
