He produced it, and from what I heard on the commentary on the DVD, he had the ideas for a few of the really funny scenes in the movie.

Everyone should watch the commentary on it, by the way. It's fucking hilarious. It's just all those guys from the movie talking about it whilst high as hell. That guy that played "Dante" was ripping bongs, too... : )
