As a gymnast, obviously I watch a lot of gymnastics videos. I've seen a lot of crazy things in my day. :-P Still, I have never seen anything like this.
Granted, the craziest part isn't gymnastics. I can't believe he bounces on his back all the way to the ceiling!! And he definitely almost hit his head on that last flip. Wow.
Pure craziness! But you're awesome, guy.
No one try this at home. ;)
