I went to a sneak of Johnny Knoxville in "The Ringer" last night. A movie where a guy poses as a retard in order to compete in the special olympics, thinking it'd be easy. Other than it being alot like the SouthPark episode, it was pretty damn funny.
It went off to a slow start, not a whole lot to laugh at until he's decided to compete. The cast was great, and once it got rolling it was a riot. Of course with Knoxville being cast there will be a ton of punches to the crotch, but damnit it's funny.
BTW I'm sure a ton of people will will say the movie makes fun of the mentally challenged, but anyone who does hasn't seen the movie. The only retard in the movie is Knoxville.
