              pole. They try to measure its height by lining up their thumbs and 
              then turning the thumb 90 degrees and marking a spot on the ground. 
              Then they try to use its shadow and trig functions, but no luck. 
            A engineer 
              comes by and watches for a few minutes. He asks one of the managers 
              what they're doing. 
            "We're 
              trying to calculate the height of this flag pole." 
            The 
              engineer watches a few minutes more and then, without saying a word, 
              he walks over, pulls the pole out of the ground, lays it down, measures 
              it, writes the measurement on a piece of paper, gives it to one 
              of the managers and walks away. 
            The 
              manager looks at the paper, snickers and says to the other managers: 
              "Isn't that just like an engineer?! We're trying to calculate 
              the height and he gives us the length."  |
