A man coughed violently, and his false teeth shot across the room and smashed against the wall "Oh, dear," he said, "whatever shall I do? I cant afford a new set" "Dont worry," said his friend "Ill get a pair from my brother for you" The next day the friend came back with the teeth, which fitted perfectly "This is wonderful," said the man "Your brother must be a very good dentist" "Oh, hes not a dentist," replied the friend, "hes an undertaker"
