The boy thought for a few minutes and then asked, "Dad, how
do fish breath underwater?"
Once again the father replied, "Don't rightly know, son."
A little later the boy asked, "Why is the sky blue?"

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 don't ask questions ... you'll
never learn anything!"
