Knock, knock
Come on in
No, knock knock
What?
It's a joke

Knock knock
Who's there?
Knocked up
Knocked up who?
Knocked up you

Start getting ready
There is no point in your trying to hide
The one you run from
Already nestled inside
Watch in amazement
Your transformation has just begun
You'll barely resemble yourself
And Mother Nature is done

Your belly will swell
Your feet will as well
Your skin will be stretched to the heavens
Scars left behind to remind you of knocked up you
Your hair will grow thick
Your mornings get sick
Your body building the placenta
Full frontal eclipse, baby, this is knocked up you

Knock, knock
Who's there?
Knocked up
Knocked up who?
Knocked up you

In your fertile ground the seed will sow
And from this moment you'll never be alone
Your pregnancy brain won't make you forget it

La la, la la
La la, la la
La la, la la
Lalalalalalalala

Acid reflux is first
Then bladders go burst
Surprise incontinence
Back aches and headaches
It's all for the knocked up you
Your hemorrhoids will itch
And you'll be a bitch
Then be called one behind your back
Your symptoms never seem to stop
For the knocked up you

Knock, knock
Who's there?
Knocked up
Knocked up who?
Knocked up you
