For better or worse, MTV is funding a bumbling cast of idiots that includes Johnny Knoxville, Bam Margera, Chris Pontius, Dave England, Steve-O, Brandon Dicamillo, Ehren McGhehey, Jason "Wee Man" Acuna and Ryan Dunn to play with poo and dress in a variety of men's undergarments. Hosted by Johnny Knoxville, Jackass features a startling array of silly pranks, ridiculous stunts and a bunch of other stupid crap. "It's just a lot of fun," said Knoxville, after showering naked with a roomful of men for the fifth or sixth time during the show's production. Never before has arrested development looked like so much fun. Jackass is co-produced and created by Johnny Knoxville, Spike Jonze and Jeff Tremaine.
