Along with Knoxville, the show featured new stars Chris Pontius, Steve-O and Bam Margera among others, with occasional guest appearances by other celebrities such as Tony Hawk and Brad Pitt. The show consisted of pranks such as jumping from buildings into bushes, shooting each other with paintball guns and stunt driving in golf carts. Often injuries were sustained but this just added to the entertainment.
Because of the success of Jackass, films were subsequently made which were as popular as the TV series. What makes Jackass so funny is that everything happening is real and those involved are clearly having fun, despite clearly incurring excruciating pain at times. Perhaps the reason Jackass is so fun to watch is because people find it fun to see people suffering when they know it is happening voluntarily!
