Dorothy and Scarecrow
We're off to see the Wizard, The Wonderful Wizard of Oz.
You'll find he is a whiz of a Wiz! If ever a Wiz! there was.
If ever oh ever a Wiz! there was The Wizard of Oz is one because,
Because, because, because, because, because.
Because of the wonderful things he does.
We're off to see the Wizard. The Wonderful Wizard of Oz.
Dorothy
Why, it's a man! A man made out of tin!
Scarecrow
What?
Dorothy
Yes.
Tin Man
Oil can!
Dorothy
Did you say something?
Tin Man
Oil can!
Dorothy
He said Oil can.
Tin Man
Me - e, me - e-, My- mmm-my, my, my, my goodness. I can talk again!
Dorothy
Well, you're perfect now.
Tin Man
Perfect? Oh - bang on my chest if you think I'm perfect. Go ahead - bang on it!
It's empty. The tinsmith forgot to give me a heart. All hollow.
