[Intro: Captain Underpants]
Tra la la

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

[Pre-Chorus: Weird Al Yankovic, Captain Underpants]
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: Weird Al Yankovic, Captain Underpants]
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: Weird Al Yankovic, Captain Underpants]
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: Weird Al Yankovic]
Snap your fingers and he'll be right there
That freaky bald dude in his underwear
He'll drop his trousers and he'll fight to save the day, the day, the day

[Pre-Chorus: Weird Al Yankovic, Captain Underpants]
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: Weird Al Yankovic, Captain Underpants]
Underpants (Hey, 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: Weird Al Yankovic, Captain Underpants]
Oh (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
