Nutcase

You're a hard nut to crack,

Meant to be broken open.

I know not what's inside you,

Or if you've a kernel of truth.

Have you got any substance,

Or are you rotten at the core?

Your shell is a false front,

Hiding a hollow underneath.

Oh precious little walnut brain

Trapped in narrow bounds,

What would you think you are,

Couldst you think anything at all?
