Once, there was a respectable Professer. He gave lectures and attended meetings all day.
'I'm so tired. If only the lecture tomorrow could be postponed,' he said to his chauffeur. His Chauffeur had followed him for almost a decade, he was very loyal; and they looked alike. And so the Chauffeur suggested,' Professer, I've heard your lectures a thousand times. I also look like you to. Maybe, I can replace you at tomorrow's lecture.'
The Professer agreed. The next day, the Chauffeur gave the lecture expertly and answered all those questions too while the real Professer stood behind the crowd, pretending to be his chauffeur.
One Professer called Quinn was envious towards the Professer. So, he asked a very hard question which the Chauffeur did not know the answer to.
The Chauffeur simply smiled and answered, 'Quinn, that question is so simple I will ask my driver in the back to answer it.'
