Ooh. It's dark down here, isn't it? They say that the old caretaker of this place went absolutely crazy. Chopped up his entire staff - of robots - all of them robots! They say at night you can still hear the screams - of their replicas. All of them functionally indistinguishable from the originals... No memory of the incident... Nobody knows what they're screaming about. Ab-solutely terrifying. Though obviously not paranormal in any meaningful way.

The lab boys just informed me that I should not have mentioned the control group. They're telling me I oughta stop making these prerecorded messages. That gave me an idea - make more prerecorded messages! I pay the bills here; I can talk about the control group all damn day.

I hope you brought something stronger than a portal gun this time. Otherwise, I'm afraid you're about to become the immediate past president of the Being Alive Club. Ha, ha.

Just a heads up: we're gonna have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest - we're throwing science at the wall here to see what sticks. No idea what it'll do. Probably nothing. Best-case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out.

All right, I've been thinking, when life gives you lemons, don't make lemonade! Make life take the lemons back! Get Mad! I don't want your damn lemons! What am I supposed to do with these? Demand to see life's manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I'm the man whose gonna burn your house down - with the lemons! I'm gonna get my engineers to invent a combustible lemon that'll burn your house down!
