Garry: I know you gentlemen have been through a lot, but when you find the time, I'd rather not spend the rest of this winter TIED TO THIS FUCKING COUCH!

Clark: I dunno what the hell's in there, but it's weird and pissed off whatever it is.

MacReady: I know I'm human. And if you were all these things, then you'd just attack me right now, so some of you are still human. This thing doesn't want to show itself, it wants to hide inside an imitation. It'll fight if it has to, but it's vulnerable out in the open. If it takes us over, then it has no more enemies, nobody left to kill it. And then it's won.

*Norris' head grows legs and tries to walk away.*
Palmer: You gotta be fucking kidding.

MacReady: Yeah, fuck you to. *throws TNT at the alien*

Childs: You're gonna have to sleep sometime, MacCready.
MacReady: I'm a real light sleeper, Childs.

Childs: If I was an imitation, a perfect imitation, how would you know it was me?

Garry: This is pure nonsense. It doesn't prove a thing.
MacReady: I thought you'd feel that way, Garry. You were the only one who could've gotten to that blood. We'll do you last.

MacReady: Now I'm gonna show you what I already know.

MacReady: Why don't we just wait here for a while... see what happens.

MacReady: Cheating bitch. *pours alcohol into the computer*

MacReady: Yes, Garry. They dig it up. They cart it back. It gets thawed out, wakes up. Probably not in the best of moods ...

MacReady: Coz it's different than us, see? Coz it's from outer space. What do you want from me?
