Anything else my lord

A small boy was standing in a street and was trying to ring the bell of a house. His hand was not reaching up there so he was trying to jump. An old man enters the street and as he sees that child unabling to ring the bell he smiles and turns up to the boy and ring the bell twice and says " Anything else my lord ?" The child replys sharply " Now run quickly before they come out and beat both of us ".
