I heard the title of this show many times in my youth (through bullying mainly, which is unfortunate), and then I was introduced to it following the movie. Basically, a bunch of American performers film each other, sometimes with hidden camera, performing stunts and pranks on each other and on the public. The stunts can often involve being injured or doing disgusting things with almost no thought for health and safety, and the pranks are always hilarious to see play out either on the performers or on the public for their reactions. Starring Johnny Knoxville, Bam Margera, Steve-O, Chris Pontius, Ryan Dunn, Ehren McGhehey, Preston Lacy, Jason Acuña aka "Wee Man" and Dave England, with appearances from Brandon DiCamillo, co-creators Jeff Tremaine and Spike Jonze (director of Being John Malkovich and Her), Bam's parents Phil and April Margera, Rick Kosick, Chris Raab aka "Raab Himself", Dimitry Elyashkevich, skateboarder Tony Hawk, Manny Puig, Rake Yohn, Stephanie Hodge, and Jess Margera (Bam's brother), with guest appearances from Brad Pitt and Shaquille "Shaq" O'Neal.

The performers deliberately doing things to hurt themselves and each other, often crashing into things, is cringing and looks painful and dangerous, and should not be tried at home. But you cannot help but laugh at it, because the performers all have a great sense of humour, and there are some genuinely ingenious pranks on the public, it is a significant part of in 2000s American popular culture, and a most watchable reality comedy show. The Christmas Special was number 49 on The 100 Greatest Christmas Moments. Good!
