Parkour is a lot of things, but mostly it's a great way to convince your parents that you have serious problems with hyperactivity, and need to wear a helmet at all times. Just kidding, it's actually a French-created combination of dance, gymnastics, walking, and (I assume) caffeine. You probably got a YouTube clip of it sent to you a few years ago, but now that it's the next big thing in China (above), it's about to get a lot more extreme. China, of course, is the home of Kung fu. Imagine if they had Parkour in Bruce Lee's time. Acutally, scratch that. People probably weren't bored enough to invent it then.

But that's not the only place Parkour is thriving. Here are some other places the "Internet sensation of 2004" is still alive and well:

Scranton, PA:

As you'll recall, Andy, Dwight, and Michael took it upon themselves to bring Parkour to the Mid-Atlantic region, with some misguided "cartwheels" and a failed refrigerator box sequence. But "The Office" isn't the only TV show with a Parkour fascination.

Studio 6B, Rockefeller Center, New York City:

Jimmy Fallon had some Parkour specialists invade his studio a few months ago, and they promptly used his set like a giant jungle gym. Insert "This is why 'Late Night' can't have nice things!" joke here.

English Phys. Ed Classes:

Last March, "The Early Show" filed a report on Parkour, and the health benefits of it. Adults enjoy it as a work out, kids as a way to get out of gym class. Win, win!

Paper:

If Parkour is truly going to be a cultural phenomenon, it needs fan art, and short of a black velvet painting of a man cartwheeling off a pedestrian bridge, this animation is an acceptable (and impressive) substitute.
