There was once a large, fat woman who had a small, thin husband. He had a job in a big company and was given his weekly wage s every Friday evening. As soon as he got home on Fridays, his wife used to make him give her all his money, and then she used to give him back enough to buy his lunch in the office every day. One day the small man came home very excited. He hurried into the living-room. His wife was listening to the radio and eating chocolates there. "You'll never guess what happened to me today, dear," he said. He waited for a few seconds and then added, "I won ten thousand pounds on the lottery !" "That's wonderful!" said his wife delightedly . But then she thought for a few seconds and added angrily, "But wait a moment! How could you afford to buy the lottery tickets?" ===== question: The woman was pleased yet suspicious when her husband won a lottery.
