Punishment

A teenage son comes to his father and with a smirk on his face. “Dad, remember when I was younger, and you saw me kill a butterfly and you told me ‘No butter for a week.'”
“Yeah,” said the father.
“And remember when you saw me kill a honeybee later?” continued the son.
“Yes, no honey for a week for that” said the father with a smile.
“Well, I just saw mom kill a cockroach. Will you tell her or do you want me to break it to her?”
