Just when you thought "Jackass" was done -- it's back!
Johnny Knoxville will reprise his role as 86-year-old Irving Zisman in "Jackass Presents: Bad Grandpa" in a prankster film ala "Borat."
A disguised Knoxville will journey across America with an 8-year-old faux-grandson, Billy -- and the two embark on one insane (and hilarious) hidden camera trip.
Check out the trailer above to see some of their wild stunts, and the unsuspecting reactions from those who cross paths with the dynamic grandpa/grandson duo.
From sabotaging a beauty pageant, to calling people strippers and even harassing funeral mourners, the victims are surprised and shocked.
"Jackass Presents: Bad Grandpa" will hit theaters October 25. Are you excited for the movie? Tell toofab in the comment section below!
