Stop Killing!

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?'
