Heads and How to Use ‘Em

There seems to be confusion
On heads and how to use ’em.
I figured out a helpful fix
With two small, quicky tricks.

I grew some teeth inside my ears
To chew up rubbish volunteered
By talkers I don’t want to hear
And keep my thinker much more clear.

The other thing makes me more proud – 
I grew ears on teeth so I’m allowed
To hear my rubbish first and loud
And maybe chew and spit it out.

This may not be for everyone,
Some may not like what I have done
Or understand its spirit,
But I don’t have to hear it.
