Little Timmy 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, Timmy! 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 Timmy.
"Why not?" said the mother.
"Because I ate him first!"
