I would have to say a toss-up between the Meatholes series or Donkey Punch. Both are released by JM, which I love a lot of their stuff, but maybe went too far with these. I will admit I have never seen Donkey Punch, but read a review of it and one of the participants interviews on the movie. I love rough videos, but I think punching someone in the back of the head is a bit too far. As for Meatholes, I have seen only the third video in the series and decided quickly I would not buy another in this series.
