Clowns Gone Postal by Summer T Waters

Buzzy is used to being a hotshot. When his philandering catches up to him, he loses his job as dean of Harvard, he loses his wife, and he loses his house. He's stuck paying alimony, so he needs a job and quick. When his neighbor tells him about how much a clown makes, he decides to become a clown.
One day, after losing his position after a birthday party gone wrong, He meets with his colleagues at the Laughing Clown Pub to drink away his woes. Mimes enter the premises and hurt the feelings of one of the other clowns. Buzzy decides he's tired of being the butt of the joke. When one of the mimes turns against his own kind, they all decide to go postal and take revenge on those who have wronged them, while planning to wage war with the mimes. Things get intense and wild until they end in a bloodbath to end all bloodbaths! Will the clowns win the war, or will they be wiped out?

This is an extreme horror novel, and is not suitable for those under 18, the weak-stomached, or the easily offended.
