A new red-band trailer for Bad Grandpa is now available.  Why is it red-band?  It might have something to do with 86-year-old Irving Zisman (Johnny Knoxville) getting his penis caught in an ATM.  Or maybe it's the scenes of Zisman giving his eight-year-old grandson Billy (Jackson Nicoll) alcohol.  Then again, it could be all the cussing caused by Zisman pissing off innocent bystanders with his childish antics.  Whatever the cause, the effect is sure to be audiences laughing their asses off when Bad Grandpa opens this Friday, October 25th.  Hit the jump to watch the new trailer.

Watch the new red-band trailer for Bad Grandpa below:

Synopsis:

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.
