A famous psychiatrist met with a vice-governor of the region during a scientific conference.
Vice-Governor: Doctor, could you please tell me if there is an easy way to distinguish a normal person from an idiot?
Psychiatrist: That’s easy. You need to ask the person a simple question. If he has difficulty answering it, then you have your answer.
Vice-Governor: What is the question?
Psychiatrist: Captain Cook made three voyages around the world and passed away during one of them. During which voyage did he pass away?
Vice-Governor: Well, I am not good with history
