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
