A true story

I heard this from one of my professors. To protect him, no names will be revealed. This professor was about to get married. He went to the jewelers to get a wedding ring for his fiancee. The jeweler told him that he can have the inside of the ring engraved with the name of his fiancee for an additional $20 (remember, this was a LONG time ago). He said, "But that will reduce the resale value!" The jeweler was aghast. He said, "How can you say such a thing. You are a butcher!" "No," replied the professor, "I am an economist"."
