The Ryley Rule.

His kitchen looks clean.   christine3

I hope you have not inadvertently revealed a sexist bias in the society: That a man in a clean kitchen either doesn't cook or has someone clean up after him when he does. 

Be it known to all people: He (gender intentional) who cooks cleans up to Mrs. Ryley's standards. 

This is affectionately known as the Ryley rule by the men in my family most of who do much of the cooking for the family.  Mrs. Ryley was a fastidious housekeeper.  Her traditional husband quickly gave up his aspirations to be a gourmet chef when faced with this rule, but her sons did their share of the cooking under it.
