Goof: Dr. Doofenshmirtz's evil plan is to write his name in the Ozone layer so that when the sun shines through it, it would burn his name into the Earth. He illustrates this by showing two slides, one of his name in the sky, the other of it being burned on the ground. The problem is that both slides show his name being properly written, when in actuality, the name in the sky would have to be written backwards in order for the name on the ground to be read properly.
Chorus: (singing) Doofenshmirtz walks to the diner.
Heinz: I just called in a to-go order for Doofenshmirtz.
Waitress: Hey, Vic. You got an order for Doofeyberg?
Heinz: No, no, no! Doofenshmirtz. Heinz Doofenshmirtz. Surely, you've heard of me.
Waitress: Okay. Order for Hans Doofensmit. Is that right?
Heinz: No, Doofenshmirtz! Doofen-- My brother's the mayor!
Waitress: Roger Doofenshmirtz is your brother?
Heinz: Yes, Doofenshmirtz!
Waitress: And your name is...?
Heinz: HEINZ Doofenshmirtz!
Waitress: Do we have an order for a Hans Doofenblatz?
Heinz: GRRRR! (beings to storm out of the diner) Mark my words! You will remember the name of Heinz Doofenshmirtz. HMMMF! (Leaves, then opens the door again) Could I still get my whole wheat on rye?
Waitress: Sure, what's your name?
Song: Ain't No Kiddie Ride.
