“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.”
