A sadist, a masochist, a serial killer, a necrophiliac, a zoophiliac and a pyromaniac are sitting in the garden at a psychiatric hospital.
They couldn't think of what to do to pass the time and as they were getting very bored, the zoophiliac says, "Why don't we shag a cat?"
So the sadist says, "Yes! Let's go and shag a cat and then torture it!"
The serial killer agrees, "Yeah, let's shag it, torture it and afterwards kill it!"
The necrophiliac jumps in excitedly, "Yeah, yeah, let's shag it, torture it, kill it and then shag it again!"
The pyromaniac, with relish, adds, "Ooh, let's shag it, torture it, kill it, shag it again and after that, we can set it on fire!"
They sit for a few moments, pleased with themselves, and turn to the masochist and say, "And don't you have anything to say?"
The masochist looks at them all and says, "Meeeoow"
