In true YouTube fashion, a kid almost paralyzed himself attempting to recreate Felix Baumgartner's space jump.  Inspired by Baumgartner, Fhat Sam attempted to jump from a 15 ft. roof onto a large yoga ball.  All was going as planned until the ball began to roll slightly backward as Sam was jumping.  Sam landed a few feet in front of the ball ass first.  Even if this stunt went as planned, we didn't see a favorable outcome for the stunt man.  

See what Free Beer and Hot Wings had to say about this idiot below.
