A zoophile, a sadist, a necrophile, a pyromaniac, and a masochist

A zoophile, a sadist, a necrophile, a pyromaniac, and a masochist

are all waiting at the bus stop for the bus to take them to the mental institution.

The zoophile says: "I'm bored. Let's fuck a cat!"

The sadist says: "Let's fuck a cat, then kill it!"

The necrophile says: "Let's fuck a cat, kill it, and then fuck it again!"

The pyromaniac says: "Let's fuck a cat, kill it, fuck it again, and then set it on fire!"

The masochist says: "Meow!"
