"Jackass ran on MTV from 2000 until 2002, and in that short period of time it cemented itself as one of the most famous reality shows of all-time. Its stars — including Johnny Knoxville, Bam Margera, Steve-O, and Chris Pontius — became famous with viewers for their crazy stunts and outlandish personas. Before each episode, the show carried a warning to viewers that the stunts performed on the series should not be attempted by anybody else, and with good reason! From thrashing abandoned golf courses to doing dubious things with staplers and their own crotches, these guys’ antics were pretty unbelievable." Source: definition.org
