Eighty-six-year-old Irving Zisman is on a journey across America with the most unlikely companion: his eight-year-old grandson Billy, in "Jackass Presents: Bad Grandpa". Jackass characters Irving Zisman (Johnny Knoxville) and Billy (Jackson Nicoll) will take movie audiences along for the most insane hidden camera road trip ever captured on camera. Along the way Irving will introduce the young and impressionable Billy to people, places, and situations that give new meaning to the term "childrearing". The duo will encounter male strippers, disgruntled child beauty pageant contestants (and their equally disgruntled mothers), funeral home mourners, biker bar patrons, and a whole lot of unsuspecting citizens. Real people in unreal situations, making for one really messed up comedy.

'Jackass 3D' opens with the entire cast all lined up, each wearing a different color of the rainbow, in front of a rainbow colored background, each in turn being attacked in various ways. Some of the footage is slowed down for maximal effect. This is repeated again at the end of the movie with additional explosions mixed in with gallons of water to wash away the cast- chaos is resumed. Throughout the movie the team are subjected to the usual foray of physical abuse from team members or perform hilarious stunts (including some of the more stomach turning stunts such as the Sweat suit cocktail, Toy Train Eruption and Poo Cocktail Supreme - not for the weak stomached!).

Johnny Knoxville and his crazy friends appear on the big screen for the very first time in Jackass: The Movie. They wander around Japan in panda outfits, wreak havoc on a once civilized golf court, they even do stunts involving LIVE alligators, and so on. While Johnny Knoxvile and his pals put their life at risk, they are entertaining people at the same time. Get ready for Jackass: The Movie!!

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, namely drinking beer off of Shridhar Chillai's several feet long fingernails; having one of the crew lie on a bed of nails with two snakes - one on his chest and one between the legs, as well as a decorated elephant in the background; and finally having a half-naked Indian Sadhu drink one of the crew's urine.
