Here is a story told about an American general who was a very important figure in the American army during the First World War. Everybody in the United States knew him and many people wished to have a picture or something of his in their homes.

Soon after the war the general returned to Washington. One day he went to a dentist and had six teeth pulled out. A week later the general heard that his teeth were being sold in curiosity shops as $ 5 each. On each of the teeth there was a label with the name of the general and words: “Buy these teeth and show them to your friends at home.” The general got angry.
