One day a gentleman was sitting in his office on the nineteenth floor in a building. A man came running in to his office and shouted "Jhon… your daughter Anna just died in an accident right opposite this building" The gentleman was in panic. Not knowing what to do he jumped out from his office window. While coming down when he was near the fourteenth floor he remembered he didn't have a daughter named Anna. When he was near the seventh floor he remembered he was not married yet. When he was about to hit the ground he remembered he is not Jhon.
