A Quote from Portal 2
Wheatley
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.

It's not like I have hordes of replacement monitors just lying around back here in the old warehouse that I can just wheel out and bolt back on. I didn't order in loads of spare monitors thinking some crazy woman was going to go around smashing them all. Sorry if that's my fault. Sorry if I didn't have the forethought to think "oh she might go crazy one day and smash all the monitors instead of just getting on with things". Sorry I didn't think of that.
