Back in Gimmelshtump

Back in Gimmelshtump, sung by Heinz Doofenshmirtz, takes place after Doofenshmirtz explains his scheme to Perry the Platypus ("Rollercoaster: The Musical!").

Lyrics
Dr. Doofenshmirtz: Back in Gimmelschtump

I always had to keep it real

Cause when you grow up in Gimmelshtump

Young Heinz: Your childhood is less than ideal!

Heinz: So I don't plan on how I'll crawl my way out of a gutter

No I don't!

When people ask me what I mean, I say

Di-Di-Di-Do I stutter!

Heinz: But I'm no longer a hater

Cause I got an Inator

And a over-complicated scheme

I get a couple of checks

Every month from my Ex

So I can finance my coming regime!

And though my past was a wreck

I won't let it affect

My aspirations to cause mass hysteria

Cause I'm as sure as can be

That it's my destiny

To be the ruler of the Tri-State Area!
