"I am but mad north-north-west... When the wind is southerly, I can tell a hawk from a handsaw."

"Hamlet is explaining that he is not REALLY mad, but only mad when he wants to be. Think of it as a sort of a self-imposed temporary insanity. When the wind blows north-northwest, he is loony. When it blows another way, he can tell "ca-ca" from "shinola."
Ca-ca, culo, pedo pis?
This comment is the first ,in google for the line of Shakespeare.
A really deep thought. I wonder where such a deep thought occured to him (I'm sure it is a man), I think I can smell it, and what's more I wonder how is it that it is the first entry in google. It must be the comment of a reputed literary critic, or maybe not?
I don't know, there are so many learned men in this world, and we know so little about them! It's good that google let us know about them, what would we do else? What would the world come to? Ah! now I think I understand where the world is coming to! This comment has given me such an insight!
