Two women are on a transcontinental balloon voyage. Their craft is engulfed in fog, their compass gone awry. Afraid of landing in the ocean, they drift for days. Suddenly, the clouds part to show a sunlit meadow below. As they descend, they see a man walking his dog.One of the flyers yells to the figure far below, ”Where are we?”The man yells back, ”About a half mile from town.”Once again, the balloonists are engulfed in the mist. One flyer says to the other, ”He must have been a lawyer.”The other says, ”A lawyer! How do you know that?”The first says, ”That?s easy. The information he gave us was accurate, concise, and entirely irrelevant.”

If you do some acrobatics with a little mathematics it will take you far along. If your idea’s not defensible don’t make it comprehensible or folks will find you out, and your work will draw attention if you only fail to mention what the whole thing is about. Your must talk of GNP and of elasticity of rates of substitution and undeterminate solution and oligonopopsony.
