- Robot Gunslinger: [to Peter Martin, trying to provoke a fight] Sloppy with your drink?
- [Martin tries to ignore him, unsure of how to react]
- Robot Gunslinger: [to the bartender] Get this boy a bib!
- Chief Supervisor: We aren't dealing with ordinary machines here. These are highly complicated pieces of equipment. Almost as complicated as living organisms. In some cases, they have been designed by other computers. We don't know exactly how they work.
- Peter Martin: You talk too much.
- Robot Gunslinger: You say something, boy?
- Peter Martin: I said you talk too much.
- Robot Gunslinger: Why don't you make me shut up?

- Interviewer of Delos Guests: [voiceover] Why don't you make arrangements to take our hovercraft to Medieval World, Roman World and Westworld. Contact us today, or see your travel agent. Boy, have we got a vacation for you.
- Arrivals Announcer: In trailer: Nothing can go wrong... go wrong... go wrong...
- John Blane: [surprised] I'm shot
- Peter Martin: [in disbelief] What?
- John Blane: I... I'm shot!
- [falls to the ground]
- Peter Martin: What's the matter with you?
- Technician: Hold out your hands. Lemme see your hands!... You're a guest! You really gave me a scare. Look, ah, everything's broken down! The machines have gone crazy!
- Peter Martin: You know about the machines?
- Technician: Yeah. I repair 'em.
- Peter Martin: There's one chasing me now... a gunslinger.
- Technician: Gunslinger... must be a model 404, maybe a 406. If he's a 406, he's got all the sensory equipment... Ah! it's a beautiful machine!
- Peter Martin: He's after me!
- Technician: I don't doubt it!
- Peter Martin: What can I do?
- Technician: There's nothing you can do! If he's after you, he'll get you! You haven't got a chance!
- Peter Martin: There must be something!
- Technician: Oh, don't kid yourself! There's things you could try... acid for his visual systems... noise for his hearing... no matter what you do, he'll always be one step ahead of you! You haven't got a chance!
- Peter Martin: Yes, I do.
- Miss Carrie: Well, you come to the right place. There's plenty of fun here. That's Cindy and Arlette. Arlette's from Paris. Perhaps you gentlemen are taking a liking to 'em?
- John Blane: Perhaps.
- Miss Carrie: They're real accommodating.
- John Blane: They eh, they look it.
- Miss Carrie: Why don't you just go on upstairs and we'll reckon accounts later.
- John Blane: Sounds good to me.
- Peter Martin: John, are those two girls machines?
- John Blane: Now, how can you say a thing like that. Come on.
- John Blane: [after Being Bitten By A Robotic Snake] The hell, god dammit, that's not supposed to happen!
- Interviewer of Delos Guests: What is your name?
- Janet Lane: My name is Janet Lane and I was in Roman World.
- Interviewer of Delos Guests: What is the one thing that stands out in your mind about Roman World?
- Janet Lane: Oh, well, I think it would be - The Men! I just feel marvelous. I mean it's just a warm, glowing place to be.

- Interviewer of Delos Guests: [hosting a commercial] Hi. Ed Renfrew for Delos again. If there's anyone who doesn't know what Delos is, well, as we've always said: Delos is the vacation of the future, today. At Delos, you get your choice of the vacation you want. There's Medieval World, Roman World and, of course, Westworld. Let's talk to some of the people who've been there.
- Black Knight: [as the guest picks up a piece of leftovers from one of the banquet hall tables] Hold varlet!
- Medieval Knight: Are you speaking to me?
- Black Knight: None other, sire.
- Medieval Knight: Look, I'm hungry and I...
- Black Knight: [impatiently swiping the guest's helmet off the table with his broadsword, then pointing the sword menacingly at the guest] Prepare for thy doom, thou scurrilous knave, huh?
- Medieval Knight: [backing up] Now, wait a minute. Ah, uh, can't we talk this over?
- Black Knight: What? Have you no spine, varlet?
- Medieval Knight: Well, I...
- Chief Supervisor: The rattlesnake struck a guest?
- Technician: Yeah, he was shooting at it, he missed.
- Chief Supervisor: Even so the snakes are programmed never to hit on a strike. Was the guest injured?
- Technician: Minor puncture wounds.
- Chief Supervisor: Inexcusable to injure a guest.
