Isaac Rokenson was a new recruit in the British Army. On his first day, an officer came up to him and said, “What is your name?”
“Isaac Rokenson,” he replied.
The officer shouted at him, “You must say ‘Sir’ when you answer an officer of the British Army. What’s your name?”
“Sir Isaac Rokenson,” came the reply.
