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?" "Because I ate her first!"
