Shocking both the cast and fanbase of the popular prank franchise "Jackass" (MTV, 2000-02) would have seemed an impossibility, but the deranged stunts perpetrated by one of its core members, Stephen "Steve-O" Gilchrist, frequently left that hard-boiled subset aghast. Though the "Jackass" series and films were built around outrageous, dangerous stunts, Steve-O's participation sunk to new depths of depravity with each subsequent project. He gleefully subjected himself to self-mutilation, extreme pain, animal bites and debasement for the delight of his friends and fans, which in turn generated more opportunities for Steve-O to maim himself on "Wildboyz" (MTV/MTV2, 2003-06) and a series of DVD releases. Unfortunately, Steve-O's life was even more out of control than his onscreen antics, and by 2008, he was hospitalized for drug and alcohol issues and a suicide attempt. He emerged from the experience sober, if not entirely matured, as evidenced by his participation in the blockbuster film "Jackass 3D" (2010). Regardless, Steve-O remained one of the most potent examples of celebrity excess, though thankfully, without the all-too-often sad ending that accompanied such stories.
