The head of a small industrial company posted DO IT NOW signs all around his office and plant in hopes of getting better results from his workers.

Some weeks later, when asked why he was removing the slogans, he said, "It worked too well: the bookkeeper skipped with $20,000; the chief clerk eloped with the best secretary I've ever had; three salesmen asked for raises; and the workers in the factory joined the union and are out on strike."
