Oh shit! Did that guy just hit himself with a hammer? That was my first response while watching this video. When the guy put on a ninja suit and started beating himself up, the OH SHI- factor kept increasing. It didn't really seem like he was hitting himself very hard with the hammer, and I can jump on my legs without that orange stuff and still be relatively unharmed, but shiiiiiit! It's still pretty awesome. I want to see where I can get this stuff and how much it costs.
I wonder how many 13-year-olds are going to get killed by trying to jump off huge buildings and getting run over by cars with this stuff.
