You can tell who the real sickos are!
I think this film is an expose into the minds of a lot of these comedians.
Think about it. For some of the disgusting filth that comes out of the mouths of some comedians, it just really shows what their values, thought-patterns and what they consider going too far or not far enough.
For some to add such vile detail, shows what warped and troubled minds some of these people have, if they think that such infantile humor is funny.
I prefer the comedy of someone like Jerry Seinfeld. Apparently, Seinfeld doesn't work "blue" in his comedy act. He will push the line (such as in his "Seinfeld" show, an episode about being "master of your domain"). However, it is subtle, and he doesn't use swear words to generate laughs.
When comedians swear in their act, I feel that it is a crutch because they don't have confidence in their joke-telling ability. The really funny comedians can keep it clean and tell really funny jokes, because people can relate or it is a funny situation they are describing. Something can be funny without swearing involved. Absurd situations, slapstick, pure wit, all these entertain me and make me laugh more than a blue joke ever will.
