This Is Our Battle Song

[PHINEAS & FERB CAST]
This is our battle song
As we're marching into war
This is our battle song
We're gonna give you guys what for

You might think you can defeat us
Your defenses have some heft
But the thing that we won't tell you
As you're fighting on the left
Is the left just a skirmish
A diversionary fight
We'll hide the bulk of our forces on the right
On the right
Out of sight
Of honor we're bereft
We were never on the left (Never on the left)

[SUPER SUPER BIG DOCTOR, spoken]
The fools. They're telling us their plan--in song. Get our forces over to the right!

[HENCHMEN, spoken]
Yeah, okay, boss. Uh, their right or our right?

[PHINEAS & FERB CAST]
No our right
They're hidden over in that forest
That's your left
Perhaps we shouldn't put that in the chorus
We should watch just what we say
Don't wanna give our plan away
But with subtle subterfuge
We will surely win the day
Surely win the day
You'll be lookin' the other way
It's our battle song
