One hundred superstar comedians tell the same very, VERY dirty, filthy joke--one shared privately by comics since Vaudeville.

Through outrageous, never-before-seen footage, witness the making of the Jackass crew's last go at wild stunts.

What does it mean to be a successful comedian? How far can the boundaries of taste be pushed to get a laugh? Four top comics, Ricky Gervais, Louis C.K., Jerry Seinfeld and Chris Rock, discuss and debate their craft.

Johnny Knoxville, Bam Margera, Steve-O, Wee Man and the rest of their fearless and foolhardy friends take part in another round of outrageous pranks and stunts. In addition to standing in the path of a charging bull, launching themselves into the air and crashing through various objects, the guys perform in segments such as "Sweatsuit Cocktail," "Beehive Tetherball" and "Lamborghini Tooth Pull."

The crew have now set off to finish what as left over from Jackass 2.0, and in this version they have Wee Man use a 'pee' gun on themselves, having a mini motor bike fracas in the grocery mall, a sperm test, a portly crew member disguised as King Kong, as well as include three episodes of their hilarious adventures in India.
