A father and son went fishing one day. After a couple hours out in the boat, the boy suddenly became curious about the world around him. He asked his father, How does this boat float?

The father thought for a moment, then replied, Dont rightly know, son.



The boy returned to his contemplation, then turned back to his father, How do fish breath underwater?



Once again the father replied, Dont rightly know, son.



A little later the boy asked his father, Why is the sky blue?



Again, the father replied. Dont rightly know, son.



Worried he was going to annoy his father, he says, Dad, do you mind my asking you all of these questions?



Of course not son. If you dont ask questions, youll never learn anything!
