There is a bar in our town with the name White Horse. It is Mr. Webster's. Few people went to the bar last year, but things are quite different now. There was a picture of a white horse on the door of the bar. Then a stranger came in one day, drank something, looked around the bar, and then said to Mr. Webster, "Few people come here. Take down the picture of the white horse and put up a picture of a black horse instead." "But the name of the bar is White Horse," Mr. Webster said. "Yes, but do it," the man said. Then he went out of the bar. Mr. Webster went to an artist and said, "I want a picture of a black horse." The next day a picture of a black horse was on the door of the bar instead of that of the white one. Soon after the door opened, a man came in and said, "There's a mistake on the door of your bar, and the picture is different from the same." The man looked, sat down and drank something. Then another man came in and said the same, and then another and another. A lot of people came in and said, "The picture on your door is wrong." and they all stopped and drank in Mr. Wesbster's bar.
