While musing about The Law of Fives, and how our prejudices influence our Perceived Peality, Banjo Patterson poem came to mind...

Around me where I sit the wary wombat goes
A beast of little wit
But what he knows, he knows.
The very same remark applies to me also
I don't give out a spark
But what I know, I know.
