A bus stopped near a small English town in the country. A man looked out of thewindow and saw a woman selling cakes. The man wanted to buy a cake but thewoman was far away from the bus.

The man did not want to get out himself, so he asked a little boy who was near the bus, “How much does a cake cost?”

“Three pence, sir”, answered the boy.

The man gave him six pence and said to him, “Bring me a cake, and with the otherthree pence buy one for yourself”.

A few minutes later the boy came back eating a cake. He gave the man three penceand said: “There was only one cake left, sir”.
