David Stillwell: [to Casselle] Wouldn't it be hilarious if it turned out you actually knew what you were doing?
[Talking about the Major]
David Stillwell: Those people aren't even ants to him! They're articles of commerce! And I'm the cost accountant, trying to cut down his overhead with what you and he call "progress"!
[Josephson is considering whether to side with David or the Major]
David Stillwell: Dammit, Josephson, commit! If you're not committed to anything, you're just taking up space!
Dr. Broden: But whatever that horrible thing that happened... I don't want to know about it!
David Stillwell: Broden, there's no doubt you're a brilliant scientist. But you're not much of a doctor, or of a human being, either.
Dr. Broden: [to himself, after David leaves] God knows.
Crawford Gilcuttie: I'm tired of you, David. Just give me the formula and get the hell out of here!
David Stillwell: What's the matter, Major? You seem nervous!
Crawford Gilcuttie: ...Why should I be?
David Stillwell: That's what I want to know.
[David looks around at the others]
David Stillwell: Josephson?
David Stillwell: Is that who you're worried about?
Josephson: Why should he be worried about me?
David Stillwell: Because I'm not on the hook anymore. You are.
David Stillwell: Because you've got the gun!
Ted Caselle: My secretary is out to lunch, my partner is out in a case. My name is Caselle. Who recommended you, Mr...?
David Stillwell: Stillwell. David Stillwell. I saw the sign.
Ted Caselle: What can I do for you?
David Stillwell: To open it, you can find who I am.
Ted Caselle: Sure, you are David Stillwell. That will be... hmm, ten bucks!
David Stillwell: What about your secretary? Don't you want to leave a note or something?
Ted Caselle: I will tell the truth. I don't have a secretary and there is no partner. As a matter of fact, you are my first case.
David Stillwell: [sarcastically] Terrific.
Shela: I've never understood why most people will do things in the dark that they'd never think of doing in the light.
Shela: I'm serious, if we have to lie, cheat, steal, and kill in broad daylight and have to wait until it's dark to make love, something's wrong somewhere.
Lester: [Referring to the TV] They got wrestling coming in from Chicago. I know it's supposed to be fixed, but so's everything else.
David Stillwell: Why don't you just take the set?
Lester: Eh, now that all the Westerns have gone psycho, this is the only place where you can tell who the bad guys are.
