Some guys have all the luck. For instance, Steve-O. The jackass of jackasses has turned stupid human tricks into a viable career move, most recently taking his brainless bravado on the road by turning wimps into wipeouts with his new show, "Dr. Steve-O."

But regardless of the motivation, they are driven by the singular joy of risking their lives just to keep you tuning in. So throw caution to the wind and take a chance with our look at nine of the nuttiest thrill seekers the set has to offer. What's the worst that can happen?
