- That's it! Let's do that, Burt!
- Yeah, Frank, you're right. That's what we got to do.
- One question, Frank. This guy screaming in here, you're sure he's a dead cadaver?
- Why don't you open the door and find out?
- No, that's all right, Frank. I'll take your word for that.
- If it is a reanimated body, we're going have to... we'll have to kill it.
- How do you kill something that's already dead?
- Well, how do I know, Fred? I don't know, let me think.
- It's not a bad question, Burt.
- In that movie, they destroyed the brain to kill them. Is that what they did?
- Yeah.
- What do doctors use to crack skulls with?
- Now listen to me, both of you, very carefully. Freddy, you're gonna open that door.
