My brother, the late Judge Ziglar, loved to tell the story of the fellow who went next door to borrow his neighbor's lawnmower. The neighbor explained that he could not let him use the mower because all the flights had been canceled from New York to Los Angeles.

The borrower asked him what canceled flights from New York to Los Angeles had to do with borrowing his lawnmower. "It doesn't have anything to do with it, but if I don't want to let you use my lawnmower, one excuse is as good as another."
