The mayor of San Francisco, London Breed, proudly announced Monday that she has instructed city sanitation workers to install a giant toilet handle in order to flush the city of feces and urine periodically. Rather than trying to keep up with the rapid accumulation of human waste in city streets, San Francisco Public Works employees will simply pull the giant toilet handle from time to time, causing billions of gallons of water to rush down alleys, sidewalks, and roads to keep things clean.
