Yo Seria Explicativo (El Mago de Oz)

I would be explanatory
If I had a reason
How trivial

If I had a brain
I would have no stress
Great thinking

The root of my hair
Which is shiny and very beautiful
Original creation

Burning the fuses
From the box building
A great thought

Millions of explanations
My mouth will give them
And the numbers keep coming
And so I will calculate

My head wide awake
Brilliant tool
Brain wave

Always working there
And inside building
A great thought.
