Jackass Presents: Bad Grandpa star Irving Zisman (Johnny Knoxville) may not be the best grandfather in the world, but at least he knows enough not to get behind the wheel after having too many beers. Unfortunately for Irving's grandson Billy (Jackson Nicoll), that means he literally has to cart grandpa around, as seen in the latest poster. Take a look at this one-sheet for director Jeff Tremaine's hidden camera comedy, in theaters October 25.

Jackass Presents: Bad Grandpa

86 year-old Irving Zisman is on a journey across America with the most unlikely companion, his 8 year-old Grandson Billy in Jackass Presents: Bad Grandpa. This October, the signature Jackass character 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.
