A man got on a bus and asked for a ticket to Trafalgar Square. He gave the conductor a ten-pound note, but the conductor could not change it because he had no small change. The conductor asked all the passengers for help, but none of them had any small change either. One passenger said that he had none, and the others said that they could not help him. The conductor felt very sorry and told the man that he must get off the bus because all the passengers seemed to be millionaires. Suddenly, two tramps on the bus told the conductor that they had some small change. They were the only people who could help the man with his ticket.
