A sadist, a masochist, a murderer, a zoophile, a pyromanic and a necrophile are all sitting on a bench in a mental institution. "Let's have sex with a cat" said the zoophile.
"Let's have sex with a cat and then torture it" says the sadist.
"Let's have sex with a cat, torture it and then kill it" shouted the murderer.
"Let's have sex with a cat, torture it, kill it and then have sex with it again" said the necrophile. "Let's have sex with a cat, torture it, kill it, have sex with it again and then burn it" said the pyromanic.
There was silence and then the masochist said: ''Miaow''.
