Wheatley: For God's sake, you're boxes, with legs. It's literally your only purpose. Walking onto buttons. How can you not do the one thing you're designed for?
GLaDOS: Try to get us down there, I'll hit him with a paradox.
Wheatley: Warmer, warmer, boiling hot. Okay colder, colder, ice cold, you're Arctic man. You're very cold, very, very, very cold. Look, just get on the button. Oh, that's funny is it. Oh it's funny? because we've been at this for 12 hours and you haven't solved it either so don't know why you're laughing. You've got one hour, solve it!
GLaDOS: I'll solve this puzzle for him. When he comes back I . . .
Wheatley: Aha, yes. I knew you'd solve it.
GLaDOS: Hey, moron.
Wheatley: Oh, hello?
GLaDOS: All right, paradox time. This sentence is false. Don't think about it. Don't think about it. Don't think about it. Don't think about it. Don't think about it.
Wheatley: True, I'll go true. Yeah, that was easy. I'll be honest, I've might have heard that one before though, sort of cheating.
GLaDOS: It's a paradox, there is no answer. Look, this place is going to blow up if I don't get back in my body.
Wheatley: False. I'll go false.
Speaker 3: Explosion imminent, evacuate the facility immediately.
Wheatley: Oh, I thought I'd fixed that.
Speaker 3: Warning, reactor core is at critical.
Wheatley: There, fixed. Hey, it is great seeing you guys again. Seriously. It turns out I'm a little bit short on test subjects right now, so this works out perfect. And off we go.
You have no idea what it's like in this body. I have to test all the time or I get this itch. You know, it must be hardwired into the system or something. Oh, but I'll tell you, when I do test, oh ho, man alive, nothing feels better. It's just that's why I've gotta test. That's why I've gotta test.
GLaDOS: Uh oh.
Wheatley: So you're gonna test and I'm gonna watch and everything is gonna be just fine.
Speaker 3: Warning, core overheating. Nuclear meltdown imminent.
GLaDOS: I think we're in trouble.
Wheatley: Designed this test myself. It's a little bit difficult. You'll notice the moat area there. Very deadly, extremely dangerous. Oh, yes. Oh, well done. Oh, that's tremendous. Oh, that felt really good. Oh, here's an idea. Since making tests is so difficult, why don't you just keep solving this test, same one. And I can just watch you solve it. Yeah, that sounds much easier.
Here we go! There, do it again. And, nothing. No, I can't blame you for trying. Okay, the new tests, new tests. Got to be some tests around here somewhere. Oh, here we go.
GLaDOS: All right, so my paradox idea didn't work and it almost killed me. Luckily, by the looks of things, he knows as much about test building as he does about logical contradictions.
