Query: This could have actually been funny, but it wasn't

What a fantastic concept, and what a horrible execution. South Park is a great example of how to make toilet humor work well. This movie is a great example of how ugly it is when it's done wrong. This goes below low-brow, even below no-brow; watch it and you'll wind up beating your brow against the wall. Watching such talented voices trying to make these jokes fly is as awkward and sad as sitting through a six year old's attempt to tell a dirty joke to a room full of adults.
