Video After The Jump
You really don't need to wonder whether or not this dude is on drugs. The fact he thought he could land a backflip off a 2 to 3-story building speaks volumes.
I don't see any money change hands, so basically this fool did this for free.
He remarkably lands on his feet, and even gets up and tries to walk it off like he's not in all kinds of pain.
I know he broke a couple bones in his legs -- he had to have.
