Jackass is an American reality series, originally shown on MTV from 2000 to 2002, featuring people performing various dangerous, crude, self-injuring stunts and pranks. The show served as a launchpad for the television and acting careers of Bam Margera, Steve-O, and also Johnny Knoxville, who previously had only a few minor acting roles.
Since the first episode, Jackass frequently featured warnings and disclaimers noting that the stunts performed were dangerous and should not be imitated, and that recordings of any stunts would not be aired on MTV. Such warnings not only appeared before and after each program and after each commercial break, but also in a "crawl" that ran along the bottom of the screen during some especially risky stunts, as well as showing their "skull and crutches" logo at the bottom right of the screen to symbolize the stunt performed as risky. Nevertheless, the program has been blamed for a number of deaths and injuries involving teens and children recreating the stunts.
