My Goody Two-Shoes Brother

 is the song from the episode "Tree to Get Ready". In this song of Heinz Doofenshmirtz tells Perry the Platypus that there are lots of people he hates, but it is his brother, Roger Doofenshmirtz, whom he wants to "Smother in a ton of pigeon goo!"

Lyrics
Dr. Doofenshmirtz: ''You see Perry the Platypus, my brother Roger is at the top of a very long list of people I despise. Vanessa, music please.''

I bear lots of animosity to bellhops,

They never bring my luggage up on time (hits statue of bell hop with his baton)

And taxi drivers really tax my patience,

If they vanished, would it really be a crime?

I don't like meter maids or underwater welders,

Health fanatic cooks or camera crews!

Not fond of monks; or yoga teachers,

Or sports fans in the bleachers!

And I'm not sure how I'm feeling about you!! (pigeons start cooing)

Dr. Doofenshmirtz: There are lots of horrid people on this planet,

That I would love to give a lashing to! (pigeons stop cooing)

But my goody two-shoes brother,

The favorite of my mother,

Is the one I want to smother

In a ton of pigeon goo!

Yes, my goody two-shoes brother,

The favorite of my mother,

He's the one I want to smother

Thank you, Sir! I'll have another!

He's the one I want to smother

In a ton of pigeon goo-oooooooooooooooooooooooooh!!

Dr. Doofenshmirtz (to Perry): You see, you see how I held that last note, good huh?
