Phineas And Ferb - He's A Bully (karaoke)

Confessions

Your opponent is as big as an ape so if you want to avoid being mangled
Just like him you've got to get into shape, and by shape I don't mean a triangle.
He's big, he's dumb, he's got the IQ of gum
He's got a brain about the size of a sourdough crumb.
But he'll beat on your head like it's a big bass drum
His behavior is truly unruly
He's a bully! (x2)
