There was a man who was born before his father, killed his mother, and married his sister. Yet, there was nothing wrong with what he had done. Why?
His father was in front of him when he was born, therefore he was born before him. His mother died while giving birth to him. Finally, he grew up to be a minister and married his sister at her ceremony.
In a contest, four fruits (an apple, a banana, an orange, and a pear) have been placed in four closed boxes (one fruit per box). People may guess which fruit is in which box. 123 people participate in the contest. When the boxes are opened, it turns out that 43 people have guessed none of the fruits correctly, 39 people have guessed one fruit correctly, and 31 people have guessed two fruits correctly.
The Question: How many people have guessed three fruits correctly, and how many people have guessed four fruits correctly?
It is not possible to guess only three fruits correctly: the fourth fruit is then correct too! So nobody has guessed three fruits correctly and 123-43-39-31 = 10 people have guessed four fruits correctly.

The internet did not exist when the doctor was a little boy.
