A sadist, a rapist, a murderer, a necrophiliac, and a masochist were all sitting together on a park bench.
The sadist said "hey, I got an idea. Why don't we get a cat and torture it?"
The rapist replied "yeah, we can torture it and have sex with it after!"
The murder enthusiastically chimed in "and then we kill the thing!"
And the necrophiliac added "yeah, and then we can have sex with it again after it's dead!"
They all nod in agreement, and then turn to the masochist, who looked at them all and said "Meow."
