A sadist, a masochist, a murderer, a necrophile, a zoophile and a pyromaniac are all sitting on a bench in a mental institution, bored out of their minds.
"How about having sex with a cat?" asked the zoophile.
"Lets have sex with the cat and then torture it," says the sadist.
"Lets have sex with the cat, torture it and then kill it," shouted the murderer.
"Lets have sex with the cat, torture it, kill it and then have sex with it again," said the necrophile.
"Lets have sex with the cat, torture it, kill it, have sex with it again and then burn it," said the pyromaniac.
The room went silent... then everyone turned to the masochist and asked:
"So, what's it gonna be?"
The masochist says "Meow."
