A man his wife and seven children had been out shopping and were planning to get a bus home. While waiting for the bus an blind old man with a walking stick joined them. When the bus arrived the bus driver told them there was only room for Eight more. So the man tells his wife to take the children on and he'll walk the blind man home. On the way home the blind man kept tapping his walking stick on the ground and the man said "Could you not get a piece of rubber for the end of your stick." The blind man replied, "if you had of put a piece of rubber on the end of your own stick we could have got on the bus."
