Joe was going into his usual bar before lunch when he saw a poorly dressed man fishing in a small pool of rain-water about five centimeters deep outside it.
Joe stopped and watched the man for a few minutes. He saw that most of the people who passed by him believed he must be rather mad.
Joe pitied man, so after a few minutes he went up to him and said kindly, "Hello, would you like to come into the bar and have a drink with me?"
The fisherman was delighted to accept her offer, and the two men went into the bar together. Joe bought the fisherman a few drinks, and finally said to him, "You have been fishing outside here, haven't you? How many did you manage to catch this morning, I may ask?"
"You are the eighth," the fisherman answered merrily.
