Two fathers and two sons sat down to eat eggs for breakfast. They ate exactly three eggs. Each person had an egg. How can this be?
Answer
One of the 'fathers' is also a grandfather. Therefore the other father is both a son and a father to the grandson. In other words, the one father is both a son and a father.
