During World War II General MacArthur called in one of his Army Engineers and asked : "How long will it take to throw a bridge across the river?" "Three days", the engineer told him. "Good", snapped the General. "Have your draftsman make drawings right away". Three days later the General sent for the engineer and asked how the bridge was coming along. "It's all ready", reported the engineer. "You can send your troops across right now if you don't have to wait for the plans. They ain't done yet".
