little boy asks mommy

“Mummy, mummy, what’s a pussy?” asked the small boy. His
mother went to the encyclopaedia and showed him a picture
of a cat.

“That’s a pussy,” she said.

“Mummy, mummy, what’s a bitch?” continued the little boy.
Again, mother consulted the encyclopaedia and showed her
son a picture of a dog.

But the boy wasn’t convinced so he went to his father and
asked him what a pussy was. Dad went to his magazine,
opened it at the centrefold and drew a circle.

“There you are, son,” he said, “that’s a pussy.”
Then the little boy asked him what a bitch was and dad
replied sadly, “Everything outside the circle, son.”
