Known for his outrageous trademark whip and his post-run breakdance moves, Ronnie Renner is not one to shy away from the camera. It's a good thing, because anything could have happened when he took a crack at a new step-up record while the cameras were rolling for the Discovery Channel's Stunt Junkies program. Renner's trophy room already boasts a couple of X games medals from the event, and now he can add the world record plaque to them.
