a necrophiliac, a zoophiliac, a sadist, a murderer, a pyromaniac, and a masochist are all sitting on a bench in a mental institution, bored out of their minds.
"How about having sex with a cat?" asked the zoophiliac.
"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," shouted the murderer.
"Let's have sex with the cat, torture it, kill it and then have sex with it again," said the necrophiliac.
"Let's have sex with the cat, torture it, kill it, have sex with it again and then burn it," said the pyromaniac.
Silence fell... then everyone turned to the masochist and asked:
"So, what's it gonna be?"
To which he replied, "Meow!"
