OK I saw this today. I really got some good laughs out of the movie. It was much better than I thought it would be. It is kind of a weird movie, sort of has a plot, which I do not really understand why they bothered with it, but I guess it was to hold the string of gags together. Some of the gags caught me by surprise and were really funny. Johnny Knoxville's disguise was really good.
Of course the usual disclaimer that this movie is totally unsuitable for a young audience and earns its R rating over and over again.
