Bucktoothed Monkey Mastermind [Common Meter]

I saw a bucktoothed monkey sit
on the ground all alone.
It looked the doofus - its dental-
mental shortfall shone,
but is the size of incisors
a measure of one's smarts?
Has anyone done the study,
gathered data, made the charts?

What if that dentally-outsized
primate is a dreamer-
a mastermind, a supervillain,
or just a first-rate schemer?
What if it just wants us to think
that it's a huge dimwit?
So, it doesn't show its erudition,
or its razor-keen wit.

Instead, it waits for us to be
lulled to a false repose,
so that it can show us we're all
a bunch of biased schmoes.
