Servant:-Sir, a man wants to see you.
Principal:-I receive parents only during office hours.
The particular office hours are posted on the notice-board.
Tell him that.
Servant:-Yes, sir. But it isn't parent sir.
Principal:-A pupil?
Servant:-I don't think so. He has a beard.
Principal:-Not a parent and not a pupil? Then what is he?
What is he look like? Stupid? Intelligent?
Servant:-Fairly Intelligent, I'd say sir.
Principal:-Good! Then he is not a School Inspector. Show him in.
Servant:-Yes sir.
