Watch 'Bad Grandpa' Get His Penis Stuck In A Vending Machine

The elderly get themselves into the damndest scrapes. Watching an old man get his penis stuck in a vending machine is just one of the many treasures you'll witness in the red-band trailer for Bad Grandpa. The unsuspecting public are also forced to witness Johnny Knoxville's Irving get his 8-year old grandson Billy sh*t-housed, ruin a funeral, dump a body, freak out some pretty rough-looking strippers, and leave a trail of destruction (and probably bodily fluids) in their wake. Jackass Presents: Bad Grandpa opens in theaters on Friday, October 25th, 2013.
