Steve-O
Stephen Gilchrist Glover (born June 13, 1974), better known by his stage name Steve-O, is an American-British-Canadian stunt performer, comedian, animal-rights activist, and television personality. His entertainment career is mostly centered on his performance stunts on the American TV series Jackass, its related movies, and its spin-off series Wildboyz.
Steve-O is known for his eccentric character. He has a number of tattoos, which he refers to as "dumb tattoos", including a "Your Name" written on his right buttock (in order to say "I got your name tattooed on my ass") and arguably his most memorable, a self-portrait which covers half of his back and sports the words "yeah dude, I rock!"
