The only person that concerned me in this movie was Zach Galifianakias as I have seen in a few different TV series on Comedy Central like Dog Bites Man and I thought he was dumb. Well his role in this movie he nailed and he is easily the funniest character in the movie.
This is just a great movie. It has a lot of inappropriate sick humor which I find very funny and so did the rest of the people in the theater.
I dont want to ruin any of the movie for you so all I can say is go see it. 5 out of 5 stars
