Taking on the Big Brain

"Big Brain" is a song played while the children tries to stop Baljeet Tjinder, brainwashed by a helmet invented by Phineas Flynn and Ferb Fletcher to stimulate his brain, from sending the atmosphere to the moon.

Lyrics

Be careful where you tread
You got me seeing red
I'm a mental thoroughbred
All the secrets of the universe are in my head

You won't get very far, I want to see the stars
Maybe later on I'll build a rocket to Mars
Now you're gonna feel the pain
'Cause you're taking on the big brain (Big brain, yeah!)
Taking on the big brain. (Big brain, yeah)

You're looking like you're dragging your cerebral feet
I know you're all mental midgets so I'm gonna repeat
I'm using little words to make it plain
Ain't no taking on the big brain (big brain, yeah!)
No hope of taking on the big brain (big brain, yeah!)
There's no use taking on the big brain (big brain, yeah!)
I said you're taking on the big brain (big brain, yeah!)
He's a big brain
