[Verse]
She's a semi-neurotic teenage girl of action (Doo-bee-doo-bee-doo-bah, doo-bee-doo-bee-doo-bah)
She's a feisty little redhead with a platypus's brain
You best leave her alone
She's playing MP3's on her phone
And whenever she's around, you can hear the bad guys say

[Interlude: Doofenshmirtz]
Great, now I have this song stuck in my head!

[Outro]
She's Perry
Perry, the Teenage Girl
