MacReady: I dunno, it's like this: thousands of years ago this spaceship crashes, and this thing, whatever it is... gets thrown out or crawls out and it ends up freezing in the ice.
Garry: So, the Norwegians find it, and they dig it out of the ice...
MacReady: That's right, Garry. They dig it up. They cart it back to their base. It gets thawed out, it wakes up, probaly not the best of moods, and... I don't know, I wasn't there!
Childs: How could this motherfucker wake up after thousands of years frozen in the ice?
George Bennings: And how can it make itself look like a dog?
MacReady: I don't know. Because it's different then us. Because it's from outer space. What more do you want from me? Ask Blair!
