Scatology has a long literary association with satire,    as it is a classical mode of the grotesque , the grotesque body and the satiric grotesque.   Shit plays a fundamental role in satire because it symbolizes death , the turd being "the ultimate dead object".   The satirical comparison of individuals or institutions with human excrement , exposes their "inherent inertness, corruption and dead-likeness".    The ritual clowns of clown societies , like among the Pueblo Indians , have ceremonies with filth-eating .   In other cultures, sin-eating is an apotropaic rite in which the sin-eater (also called filth-eater),   by ingesting the food provided, takes "upon himself the sins of the departed".  Satire about death overlaps with black humor and gallows humor .
I do not know what quote to start this entry off with. A bit of a cheat, but these two have worked together to create a great satiric force. South Park has set its satiric sights on just about everyone in its fourteen years. The humor is absurdist and shotgun, no one escapes without having their ludicrous aspects exposed. Even though many view it as offensive, they seem to miss that everyone is getting their fair share of abuse. To watch South Park and feel you are being unfairly targeted is to reveal your own insecurities. Whatever your religious or political standpoints, by mocking all sides, South Park asks everyone to question their beliefs and accept nothing on the basis of an outside authority.
