Johnny Knoxville and the `Jackass' crew present more idiotically irresponsible, wilfully dangerous and stomach-turningly gross stunts, taken from footage that was shot for and during the making of `Jackass 2'. This time around, the action is interleaved with sections in which the cast and crew talk candidly about their role in the chaos, and how and why some of the scenes didn't turn out entirely as they'd hoped.
