Harcourt Fenton "Harry" Mudd: Sure, these starships are really something marvelous. But men will always be men, no matter where they are.
Harcourt Fenton "Harry" Mudd: You're part Vulcanian, aren't you? Ah, well, then a pretty face doesn't affect you at all, unless you want it to. You can save it, girls. This type can turn himself off from any emotion.
Harcourt Fenton "Harry" Mudd: You're a hard-nosed one, Captain.
Kirk: And you're a liar. I think we both understand each other.
Kirk: Well, switch to bypass circuits.
Scotty: We burned them all out when we super-heated. That jackass Walsh not only wrecked his vessel, but in saving his skin...
Kirk: If it makes you feel any better, Engineer, that's one jackass we're going to see skinned.
Kirk: Computer, go to sensor probe. Any unusual readings?
Computer: No decipherable reading on females. However, unusual reading on male board members. Detecting high respiration patterns, perspiration rates up, heartbeat rapid, blood pressure higher than normal.
Kirk: Uh, that's sufficient. Strike that from the record, Mr. Spock.
Harcourt Fenton "Harry" Mudd: You see, gentlemen, just as I told you. Three lovely ladies destined for frontier planets to be the companions of lonely men, to supply that warmth of a human touch that's so desperately needed--a wife, a home, a family. Gentlemen, I look upon this work as a sacred public trust. I've devoted me whole life to it.
Computer: (scanning for truth) Incorrect.
Harcourt Fenton "Harry" Mudd: And l--I'll be running this starship. Captain James Kirk, the next orders you're taking will be given by Harcourt Fenton Mudd!
Eve McHuron: I was taking a walk, and I had to run in someplace. All your men were looking at me, following me with their eyes.
Kirk: Yes. I'll have to talk to them about that.
Eve McHuron: Hmm! I read once that a commander has to act like a paragon of virtue. I never met a paragon.
Kirk: Neither have l.
Eve McHuron: Well, of course not. No one is. But some people try to pretend.
Kirk: What are they, Bones?
McCoy: You mean are they alien illusions? That sort of thing?
Kirk: I asked you first.
McCoy: No... an alien smart enough to pull this could also keep my medical scanner from going "bleep!"
Kirk: I don't follow you.
McCoy: I don't either.
Eve: Oh, the sound of male ego. You travel halfway across the galaxy and it's still the same song.
Ben Childress: I guess I'm supposed to sit, taste, and roll my eyes. "Ooh, female cooking again." I've tasted better, by my own hand.
Eve McHuron: You're tasting some of it. I couldn't scrape your leavings out of that pan.
Kirk: But I will appear as a character witness at your trial... if you think that'll help.
Harcourt Fenton "Harry" Mudd: They'll throw away the key.
Spock: I'm happy the affair is over. A most annoying emotional episode.
McCoy: Smack right in the old heart. Oh, I'm sorry. In your case, it would be about here.
Spock: The fact that my internal arrangement differs from yours, Doctor, pleases me no end.
When Mudd's women beam on board and Spock, McCoy, and Scotty stare, the reaction shot of McCoy has him wearing his medical tunic and a Sickbay monitor screen can be seen behind him. The shot is later used properly when McCoy is in sickbay running an exam on one of the women.
When Mudd's women beam on board, the brunette (Ruth) is further to the back. Then they cut to a reaction shot of the men, then a shot of the women all lined up evenly. Then more reaction shots of the men, and then back to a shot of the women and Ruth is further to the back again.
When Spock orders Farrell to set course for Rigel 12, Farrell's insignia is missing.
Eve takes the (fake) Venus Drug and her hairstyle changes without her touching it.
