Hayata, maybe you could contract with the city to spray soap on some of the dirtier parts of the "hoods" using that method, mixing it with the soap your wife makes! Boom! Instant fix to that problem and puts bucks in your pocket ! (Of course I wouldn't mind a nominal fee for the idea)
How do you know I haven't been hired by the FBI to put microscopic trackers in the bars of soap to track ODT'ers?
Just sayin'...
