"He loved his work," his wife said, "but he told me it doesn't challenge the mind a great deal."
From the fabulous obituary of Gerald Cook, Union Square traffic warden. "To keep motor traffic motoring on Stockton (ever southbound) and O'Farrell (always eastbound), Mr. Cook would dress in costumes, wear tap shoes, wave maniacally, hop like a bunny and, on occasion, drop to his knees and plead with slowpoke drivers to get on with it already."
That sounds like the way to do it. Especially in San Francisco.
