Osama Bin Laden (while  teaching his son)

Osama Bin Laden ( while  teaching his son) – My son, just tell me the name of the present President of America.

Son – Abba, don’t you know the answer?

Osama Bin Laden – Yes, of course. He is none other than George Bush.

Son – Abba, then why are you trying to waste my time by asking this question to me?
