By the look of the video it happened a long time ago, but it's still funny. It takes some hearing problems not to hear a gun shot. Look at his surprised face when he sees the other runners pass him by!

Parkour is now the new extreme urban sport. Invented in France, it's actually a form of climbing, jumping, and doing all kinds of stunts in an urban environment. The catch is that everything has to have a nice flow to it. That said, it's time to watch this cool video, and see how some of the best guys do it! Enjoy!
