DESCRIPTION:
From the Phinas and Ferb original TV soundtrack

Lyrics:

Your opponent is as big as an ape
So if you wanna 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 the brain about the size
Of a sour-dough crumb
But he'll beat on your head
Like a big base drum
His behavior is truly unruly
He's a bully! (He's a bully!)
Yeah, he's a bully! (He's a bully!)
Well, he's a bully! (He's a bully!)
Yeah, he's a bully! (He's a bully!)
He's a bully

He's not easy to reason with
He's no rocket scientist
He's so illogical
He's a bully
Yeah!
Yeah!
Yeeaaah-yeah yeah!
