A zoophile, a sadist, a murderer, a necrophile, a pyromaniac and a masochist are all sitting on a bench in a mental institution, bored out of their minds.

"Let's about having sex with a cat?" says the zoophile.

"Let's have sex with the cat and then torture it," says the sadist.

"Let's have sex with the cat, torture it, and then kill it," shouts the murderer.

"Let's have sex with the cat, torture it, kill it and then fuck it again," says the necrophile.

"Let's have sex with the cat, torture it, kill it, fuck it again and then burn it," says the pyromaniac.

Silence took over, and then the masochist says: "Meow."
