Impress My Professor

I Must Impress My Professor is a song sung by Heinz Doofenshmirtz in "Oil on Candace", done in the style of a Broadway musical. Sixteen identical background singers join Heinz in the song, and three of them would later return for He's Eviler.

During the song, the lines in blue are sung by the background singers at the same time as Heinz's lines.

Lyrics
Doofenshmirtz: Back in class, Evil 101...

I always had so much fun...

Though the one who advised me...

Openly despised me...

Still I always tried to be number one

Well I wanted a mentor to share my world view

But I got a tormentor, I was hated, it's true

Now I have one more chance, and it could mean my advancement

So there's only one thing I must do:

I must impress my professor

Singers: (He's got to be good)

Doofenshmirtz: I must impress my professor

Singers: (He's misunderstood)

Singers: He needs validation for his evil creation

Doofenshmirtz: (Oooh-oooh)

Doofenshmirtz: Like any good evil scientist would

Doofenshmirtz: I must impress my professor to be a success

Singers: He must impress his professor to be a success

Doofenshmirtz: Or I will still be a flunky, a diploma-less monkey

Singers: Or he will still be a flunky, a diploma-less monkey

All: In the eyes of this person

Who's opinion may worsen

Doofenshmirtz: If my evil invention's not great

Doofenshmirtz: I must impress my professor!

Singers: (Impress his professor)

Doofenshmirtz: I must impress my professor!

Singers: (Impress his professor)

Doofenshmirtz: I must impress my professor

All: Before it's too late!

Background Information

 * Doofenshmirtz uses virtually the same hat and cane as seen in My Goody Two-Shoes Brother.
 * When the backround singers say the line "He needs validation for his evil creation," two of his inventions are quickly wheeled on and off-stage. If you notice closely, in order, the two inventions seen are the Freezeanator and the Monster Truck away-inator ( "It's About Time", "It's a Mud, Mud, Mud, Mud World").
