Jimmy, Michael:

Jimmy De Santa: "Hey, let's bounce."
Michael De Santa: "Bounce? We're bouncing now? Is that what we're doing? Jesus fucking Christ."

Dr. Friedlander, Michael:

Dr. Isiah Friedlander: "Your son, James. He's a good kid?"
Michael De Santa: "He's a good kid? A good kid? Why? Does he help the fucking poor? No. He sits on his ass all day, smoking dope and jerking off while he plays that fucking game. If that's our standard for goodness... then no wonder this country's screwed."

Little Jacob:

You can't shake no hands when ye fist be clenched.

Announcer, Wheatley:

Announcer: "Good Morning! You have been in suspension for nine, nine, nine, nine, nine nine..."
Wheatley: Hello?
Announcer: "This courtesy call is to inform all test subjects to vacate the Enrichment Center."
Wheatley: "Are you going to open this door? Because it's fairly urgent."

GLaDOS in Co-Op Mode:

Weighted Cubes calibrated. No variances detected. Did you know humans frown on weight variances? If you want to upset a human, just say their weight variance is above or below the norm.

GLaDOS:

Do you know the biggest lesson I learned from what you did? I discovered I have a sort of black box quick-save feature. In the event of a catastrophic failure, the last two minutes of my life are preserved for analysis. I was able - well, forced really - to relive you killing me. Again and again. Forever. You know, if you'd done that to somebody else, they might devote their existence to exacting REVENGE! Luckily, I'm a bigger person than that. I'm happy to put this all behind us and get back to work. After all, we've got a lot to do, and only sixty more years to do it. More or less. I don't have the actuarial tables in front of me.

Cave Johnson:

For this next test, we put nanoparticles in the gel. In layman's terms, that's a billion little gizmos that are going to travel into your bloodstream and pump experimental genes and RNA molecules and so forth into your tumors. Now, maybe you don't have any tumors. Well, don't worry. If you sat on a folding chair in the lobby and weren't wearing lead underpants, we took care of that too.

Cave Johnson:

All these spheres are made of asbestos, by the way. Keeps out the rats. Let us know if you feel a shortness of breath, a persistent dry cough, or your heart stopping. Because that's not part of the test. That's asbestos. Good news is, the lab boys say the symptoms of asbestos poisoning show a median latency of forty-four point six years, so if you're thirty or older, you're laughing. Worst case scenario, you miss out on a few rounds of canasta, plus you forwarded the cause of science by three centuries. I punch those numbers into a calculator, it makes a happy face.

Announcer:

Some emergency testing may require prolonged interaction with lethal military androids. Rest assured that all lethal military androids have been taught to read and provided with one copy of the Laws of Robotics. To share.

GLaDOS:

Did you feel that? That idiot doesn't know what he's doing up there. This whole place is going to explode in a few hours if somebody doesn't disconnect him. I can't move, and unless you're planning to saw your own head off and wedge it into my old body, you're going to need me to replace him. We're at an impasse.

GLaDOS:

Listen to me. We had a lot of fun testing and antagonizing each other, and, yes, sometimes it went too far. But we're off the clock now. It's just us talking, like regular people. And this is no joke: we are in deep trouble.

Wheatley after breaking 11 monitors:

They're not even your screens to break! It's vandalism! It's pure vandalism! You wouldn't do this if it was your house, would you? If I came around to your house smashin' your telly, you'd be furious. And rightly so. Unbelievable.

Wheatley after breaking 10 monitors:

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.

Wheatley after breaking 9 monitors:

Oh, there goes another one. They're not inexpensive. I'd just like to point that out. It seem unfair to smash screens. You could give them to people. Instead of smashing them, unscrew them and give them to a homeless person. I don't know what a homeless person would do with one. But you get my point. And you can't unscrew them, they're bolted in. But - just stop it!

Wheatley after breaking 6 monitors:

You know, there are test subjects in Africa who don't even have monitors in their test chambers. Why don't you think of that before you break any more of them?
