Last week, the famed team behind the Jackass franchise released the trailer to their newest effort, a film called Jackass Presents: Bad Grandpa. The movie is due out this Fall, and it stars Johnny Knoxville as Irving Zisman, a vicious and senile old man who's forced to take care of his grandson. Judging by the trailer (which you can see above), it looks like it'll be another hilarious chapter in the Jackass saga. Since the creators of the TV series and film trilogy have been such good friends of hip-hop, even collaborating with the likes of Fatlip (of Pharcyde) and Three 6 Mafia on stunts, XXL decided to pull together 20 of the best Jackass stunts of all time. Check them out.
