Nstradin's son came back from the university where he had become very smart. He learnt about logic and became a great master and philosopher. He wanted to demonstrate all he had learnt to his mother. The mother brought 2 apples. The clever son said: Mother, how many apples do you see? She replied: two apples. The son remarked: No! The logic says differently. There are three apples, look - this is apple number one, this is apple number two, and one and two is three. Nastradin heard that and came closer. He said: Very good son! Now your mother is gonna eat apple one, I am going to eat apple two and you are going to have apple three.
