One day, a bus driver was offered a handful of peanuts by an old lady, which he gratefully munched up. The old lady repeatedly gave peanuts to the driver eight more times. But on the ninth time the driver asked the old lady why she didn't eat the peanuts herself. The old lady replied that it was not possible because she had no teeth. "Why then do you buy them?" the driver asked, puzzled. The old lady answered, "I just love the chocolate around them!"
