A boy and his father were playing catch in the front yard when the boy saw a honey bee. He ran over and stomped it.
"That was a honey bee," his father said, "one of our friends. For stomping him you will do without honey for a week."
Later the boy saw a butterfly, so he ran over and stomped it.
"That was a butterfly," his father said, "one of our friends, and for stomping him you will do without butter for a week."
The next morning the family sat down for breakfast. The boy ate his plain toast with no honey or butter.
Suddenly a cockroach ran out from under the stove. His mother stomped it.
The boy looked at his father and said, "Are you going to tell her, Dad, or should I?"
