Meow

So a rapist, a masochist, a pyromaniac, a necrophile, a sadist, a pedophile, and a zoophile are all standing in a jail cell.
The rapist says, "I'd like to fuck something.".
The zoophile says, "A cat."
The pedophile says, "Even better: a kitten."
The sadist asks, "How about we beat the kitten up, and THEN have sex with it?"
The necrophile adds, "Alright let's beat a kitten to death, and then have sex with it."
Then the pyromaniac says, "Okay, how about we beat a kitten to death, light it on fire, and then have sex with it?"

The masochist says, "Meow."
