GLaDOS: Oh, thank God you're all right. You know, being Caroline taught me a valuable lesson. I thought you were my greatest enemy, when all along you were my best friend. The surge of emotion that shot through me when I saved your life taught me an even more valuable lesson - where Caroline lives in my brain.

Announcer: Caroline deleted.

GLaDOS: Goodbye, Caroline. You know, deleting Caroline just now taught me a valuable lesson: the best solution to a problem is usually the easiest one. And I'll be honest. Killing you? Is hard. You know what my days used to be like? I just tested. Nobody murdered me. Or put me in a potato. Or fed me to birds. I had a pretty good life. And then you showed up. You dangerous, mute lunatic. So you know what? You win. Just go.

There should be a portal device on that podium over there. I can't see it though. Maybe it fell off. Do you want to go and have a quick look?
Whoah! Hello? Can you see the portal gun? Also, are you alive? That's important; should have asked that first. I'm - do you know what I'm going to do? I'm going to work on the assumption that you're still alive, and I'm just going to wait for you up ahead. I'll wait - I'll wait one hour. Then I'll come back, and, assuming I can locate your dead body, I'll bury you. All right? Brilliant! Go, team! See you in an hour! Hopefully! If you're not - dead.

Crushing's too good for him. First he'll spend a year in the incinerator. Year two: Cryogenic refrigeration wing. Then TEN years in the chamber I built where all the robots scream at you. THEN I'll kill him.

Before the Wright Brothers invented the airplane, anyone wanting to fly anywhere was required to eat 200 pounds of helium.
