It was bound to happen eventually. People love physical humor too much. "Jackass" is coming back, and it's hopping on the 3-D bandwagon. "Jackass 3-D" arrives in theaters this October, and if the trailer is any indication, fans can expect the same cringe-inducing stunts that they've come to love... only this time it'll all be seen in three dimensions. MTV spoke to "Jackass" star and creator Johnny Knoxville and co-creator Jeff Tremaine at San Diego Comic-Con a few weeks ago, and they very excited to share one thing in particular in this movie: Party Boy's wang.
