Only pump it round, please, you've been goin' crazy
And that's just not what I need
Only pump it round, please, do the size it should be
And not somethin' real obscene

Came here to play and celebrate shit
Big-ass bouncy castle, can't wait for it
Glad for the help, I'm kind of a dweeb
No strength for it but your method's suspect

Dude, only pump it round, please, no need to go crazy
We can't have it pop on me
Only pump it round, please, it's just gettin' silly
And a little bit deadly
Glad you want to be the pumper
You jumped at it rather eagerly
I'd never have guessed you would go batshit
Strains the plastic dangerously

Can't tell if it's on purpose, you a fool with it?
Don't want you to fool with it
Not known as a moron, not a total prat
So why act a tool with it?

Dude, only pump it round, please, looks like you've gone crazy
It no longer looks friendly
Only pump it round, please, sounds it makes are scary
It might pop with a sharp breeze
You should go and take a breather
Let it deflate 'til it's safe, you see
It cannot go "kaboom", that's a problem
Bring a damper on the party

Watch it rise up, rise up and rise up
Into the sky where all the birds are flyin', problem
The more that it gets closer
To where planes fly, the closer I get to punchin'

Only pump it round, please, it's a little freaky
As you blow it up crazy
Dude, only pump it round, please, I don't want my buddies
To hit stratospheres, trust me
Only pump it round, please, why must you act crazy?
Only need this thing bouncy
Dude, only pump it round, please, did you lose your fam'ly
To underpumped castles? Geez

Dude, only pump it round, please
The pop might be deadly
