One very versatile patriot sold Uncle Sam twelve dozen 48-inch wrenches. Oh, they were very nice wrenches. The only trouble was that there was only one nut ever made that was large enough for these wrenches. That is the one that holds the turbines at Niagara Falls. Well, after Uncle Sam had bought them and the manufacturer had pocketed the profit, the wrenches were put on freight cars and shunted all around the United States in an effort to find a use for them.
