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