When Beyonce fell, it was both funny and embarrassing. But when skateboarder Jake Brown tumbled -- it was almost deadly!

At the opening night of the X-Games, the boarder took a terrifying 50-foot free-fall while doing a run, slamming his back onto the ramp -- where he was motionless for nearly five minutes. So heavy.

Still crazier is that despite the terrifying fall -- Brown then walked away from the ramp -- and ended up placing second in the "Big Air" competition! Gnarly!
