The Greatest Salesman in the World

I lost my pocket knife a few weeks ago. I was in a hardware store that had "reconditioned" (they just looked used to me) Swiss Army knives for approximately 1/3 the cost of new. The salesman had two I liked. The main difference between them was that one had a corkscrew and one had scissors. I was leaning toward the corkscrew when the salesman said, "Well, I have taken informal surveys of customers, and most say they only use a corkscrew 3-4 times during the life of the knife, whereas they will use scissors fairly often."

I looked at him in wonder. "To use a corkscrew 3 or 4 times"? I gasped, I gawked. "3 or 4 times"? I regasped and regawked. "My good man, I'll take two of them."
