Tom 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.
   Tom 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.
   Tom pitied the 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 his offer, and the two men went into the bar together. Tom bought the fisherman a few drinks, and finally said to him, "you’ve been fishing outside here, haven’t you? How many did you manage to catch this morning, if I may ask?"
   "You are the eighth," the fisherman answered happily.
8. What was the poorly dressed man doing when Tom saw him?
