Walking along a street a man was attracted by frightened screams from a house. Rushing in he found a mother frantic because her little son had swallowed a quarter. Seizing the child by the heels, he held him up, gave him a few shakes, and the coin dropped to the floor. The grateful mother was lost in admiration. You certainly knew how to get it out of him, She said. Are you a doctor? No, madam, the man replied, I m from the Internal Revenue Bureau.
