I know what we're gonna do today,
Though it might sound just a bit cliché.

We can build a roller coaster,
But this time with songs and dancing!
'Cause when we're back in school come next September,
And they ask us, we can both remember
Every cool and clever thing we did all summer long, and glancing

Back we're gonna be so glad that we
Didn't sit all day and watch TV,
I don't think anyone can disagree
The world is possibilities
And that's what makes me say

Hey Ferb!
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today!

Phineas and Chorus: Hey Ferb!
Background singers: Boredom is something up
With which I will not put

Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today!

Hey Ferb!
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today!

Boredom is something up with which I will not put
Hey Ferb!
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today
Hey Ferb, I know what we're gonna do today!
Hey Ferb!
