Thinking his company had too many rules, an office worker decided to do something about it. So he posted an official-looking notice next to the pencil sharpener. Next

sharpened. After two weeks, seventeen people had signed the log. The worker who

had thought it up had also signed it - twice. "Everyone else was doing it, so I

thought I should sign it, too," he explained.
