Doofenshmirtz2: Do you want some rice pudding?

Doofenshmirtz: Blech, no, that's gross!

Doofenshmirtz2: It was a test. Almond brittle?

Doofenshmirtz: Ooh, I love it the most!

Doofenshmirtz2: Me too!

Doofenshmirtz: Do you collect coins?

Doofenshmirtz2: Yeah, just in case

Vending machines become the

Both: Dominant race

I've been alone all these years

With my irrational fears

Doofenshmirtz: ''But not the vending machine thing. That's gonna happen.''

Doofenshmirtz2: But now before me I see

Both: Someone with whom I agree

I've found a brand new best friend and it's me

I've found a brand new best friend and it's me

Doofenshmirtz2: Hmm, I thought I'd be taller

Doofenshmirtz: I've been told I slouch

I thought I'd have both my eyes, y'know...

Doofenshmirtz2: It's in this pouch

Doofenshmirtz: Ouch!

Doofenshmirtz: You know, I can't help but notice that your scar goes over your eyepatch.

Doofenshmirtz2: Yeah...

Doofenshmirtz: [pause] ...Nothing...

Doofenshmirtz: Do llamas weird you out?

Doofenshmirtz2: Yeah, are they camels or sheep?

Doofenshmirtz: No, no, I meant Lorenzo Doofenshmirtz2: Oh, that's right

Both: He played Meap!

Now I know all about you

And you know all about me'' '' Doofenshmirtz: Ooh-wee-ooh

Both: And now before me I see

Someone with whom I agree

I've found a brand new best friend and it's me

I've found a brand new best friend and it's me

Now that I've found you

We can be a duo

Doofenshmirtz: That's right.

Both: Twice the evil

Double Doofenshmirtz

Doofenshmirtz: Coming at you Fridays!

Doofenshmirtz-2: What's that, are we doing a TV show together?

Doofenshmirtz: "Oh no. It just sort of sounded like that. Well, I mean, we could. We should!"

Doofenshmirtz-2: Hmm, maybe we're not so much alike"  Doofenshmirtz: "That can be your catchphrase! You're the grumpy one. [Pokes him] Ah?"
