[After Bubbles sprays "Flowers are pretty... dumb!" on a wall]
Butch: For a second there, I thought you were turning girly on us.
Brick: Yeah! And "dum-buh"? Geez, Boomer, if you're gonna do graffiti, at least spell the words right! Sheesh, talk about "dum-buh".
Butch: Yeah! What a "dum-bee"!
[Brick & Butch laugh]

[After changing everyone in Townsville into dogs with the Anubis Head]

The Rowdyruff Boys: Yeah!
Mojo Jojo: Butts planted in the soil of nobility!
The Rowdyruff Boys: Yeah!
Mojo Jojo: Butts nestled between the pillars of peace and love! The butts you want to kick are the butts of the Powerpuff Girls!
The Rowdyruff Boys: Let's get 'em!
