Crandall's Law maintains that ""All tour buses arrive at the same time""; apparently rule books do too. Coming close on the heels of Dickson's The Official Rules (p. 1162), this reminds us of the law of diminishing returns. But New York Timesman Faber has not broken The Fifth Rule (""You have taken yourself too seriously"") and his reasonably organized collection of precepts uncovers many that ring true. Like Meskimen's Principle: ""There's never time to do it right, but always time to do it over."" Or The First Law of Expert Advice: ""Don't ask a barber if you need a haircut."" Or The Harvard Law of Animal Behavior: ""When all conditions are known and controlled, the animal will behave as it damn well pleases."" Faber sees Parkinson as the beginning of the line and, like Dickson, credits Peter for continuing the tradition. He also quotes from several of the same sources, including Wall Street Journalist Alan Otten. Which may leave both Dickson and Faber pondering Arney's Law: ""Every time you come up with a great idea, you will find someone else has thought of it first.
