Baby-worm

Little Johnny sat playing in the garden. When his mother came out to collect him, she saw that he was slowly eating a worm. She turned pale. "No, Johnny! Stop! That's horrible! You can't eat worms!" trying to convince him further, "Now the mother worm is looking all over for her nice baby-worm."

"No, she isn't," said Johnny.

"Why not?" said the mother.

"Because I ate her first!" answered Little Johnny.
