We're gonna draw a little bit of everybody's blood... 'cause we're gonna find out who's The Thing. Watchin' Norris in there gave me the idea that... maybe every part of him was a whole, every little piece was an individual animal with a built-in desire to protect its own life. Ya see, when a man bleeds, it's just tissue, but blood from one of you Things won't obey when it's attacked. It'll try and survive... crawl away from a hot needle, say.
Dr. Blair: [throwing a fit in the radio room] You guys think I'M crazy! Well, that's fine! Most of ya don't know what's goin' on around here, but I'm damn well sure SOME of you do!
Childs: He got most of the chopper and the tractor, and he's killed the rest of the dogs.
MacReady: Garry, wait a minute, wait a minute. Now, Childs, go around to the map room door. Talk to him.
MacReady: Norris, get a table from the lab.
Dr. Blair: D'ya think that thing wanted to be an animal? No dogs make it a thousand miles through the cold! No, you don't understand! That thing wanted to be US! If a cell gets out, it could imitate everything on the FACE OF THE EARTH! AAAAND NOTHING can stop it!
Childs: Okay, Blair. Come on, man, you don't wanna hurt anybody.
Dr. Blair: I'LL KILL YOU!
