The Anal Polyps
Shrouded in mystery, not much is known about the socially deviant group know only as the Anal Polyps. Some people believe that the AP was formed by a satanic cult in the late 1800's. Others think that it is a secret government entity, created in the early 1960's to develop a new toxic virus that would be used in biological warfare to completely annhilate an enemy.
The story I tend to believe is that the Anal Polyps exist to maintain the world's collective sense of humor, which has been fading steadily since the dawn of the modern era.
