[Intro]
Tra la la!

[Verse 1]
Are you worried 'bout impending doom?
Those evil villains got you filled with gloom?
Don't you fear, there's a hero in the sky, the sky, the sky

[Pre-Chorus 1]
It's not a bird and it's not a plane
And it's not an egg salad sandwich
It's the waistband warrior
Hear his mighty battle cry
Tra la la!

[Chorus 1]
Underpants! Hey, watch out, crime!
It's Captain Underpants! It's wedgie power time!
Na-na-na-na-na, Captain Underpants, yeah, yeah, yeah
Faster than a speeding waistband!
Underpants! He's busting down doors
Captain Underpants! While wearing just his drawers
Na-na-na-na-na, Captain Underpants, yeah, yeah, yeah
More powerful than boxer shorts!

[Post-Chorus 1]
His name is Under, Under, Underpants!
I'm saying Under, Under, Underpants!
Oh by some unlikely chance
Captain Underpants is his name
Tra, tra-tra, tra-tra la la!
[Verse 2]
Snap your fingers and he'll be right there
That freaky bald dude in his underwear
He'll drop his trousers and fight to save the day, the day, the day

[Pre-Chorus 2]
There he goes in his dashing cape
Here he comes in his tighty whiteys
All the bad guys soil themselves every time they hear him say
"Tra la la!"

[Chorus 2]
Underpants! Yeah, who's that hunk?!
Captain Underpants! Is that cotton pre-shrunk?
Na-na-na-na-na, Captain Underpants, yeah, yeah, yeah
Now it is time to fly again!
Underpants! Suspend your disbelief
Captain Underpants! He'll save the world in his briefs
Na-na-na-na-na, Captain Underpants, yeah, yeah, yeah
To the skies! Wow!

[Post-Chorus 2]
Under, Under, Underpants
I'm saying Under, Under, Underpants
Check out that superhero stance
Captain Underpants is his name
Stand down, Poopypants!
Oh, Under, Under, Underpants!
He's Captain Under, Under, Underpants!
By some crazy circumstance
Captain Underpants is his name
Tra, tra-tra, tra-tra la la!
