Even though I'm not an Extreme Sports guy, I do love watching the X-Games.  I wouldn't call what they do a sport, but it's a fantatstic athletic feat, and some of the things they do are just insane.  This video isn't a gold medal performance, but it kicks ass.

Don't worry.  The guys is alright.  Well, maybe not alright, but he's going to be fine.  Something tells me there is some pretty good medical grade stuff there.
