Candace, Jeremy and Phineas sing Team Rocket's original motto. Plus, they're also singing Double Trouble.
(Candace is symbolized by 'C', Jeremy, 'J', Phineas 'P' and Dr. Doofenshmirtz, 'Dr. Doof'. Dr. Doofenshmirtz is the boss, and Perry is Pikachu and what isn't said by anyone is substituted with 'Chorus'). This is edited in which they say their names and not what is said during the motto.
Dr. Doof: This is the boss and I'm sick of waiting. I want Pikachu! And this time, don't screw it up!
Chorus: Prepare for trouble, make it double. Prepare for trouble, make it double.

P: Phineas, now that's a name.
C: Putting the do-gooders in their place,
J: Team Rocket.
All: We're in your face!
This is basically an idea I had. Basically Dr. Doofenshmirtz wants Pikachu [Perry] and he sends Candace [Jessie], Jeremy [James], and Phineas [Meowth] to capture him. I used Phineas because I didn't know who would best personify him. Please tell me if another P&F character would best personify Meowth.
