Fake Japanese Ninjas Doing Their Goofy Shit All Over Tokyo

In all honesty I can't decide whether I like these goofballs or not. Part of me says that what they're doin' is pretty athletic and there's always the risk of some serious faceplants. The other part of me says that they're just a bunch of dickwads that have taken silly shit like cartwheels and skipping to the next level. I know, I know, it's called "Parkour" and people all over the globe do it. But really, what's the point? And how can you tell who's really good and who's just okay? Can someone please invent a scoring sytem for this controlled spaziness? Maybe then I can make up my mind. Pay attention!
