Catherine: You know I don't like to wear any underwear, don't you, Nick?
Dr. McElwaine: Nick, when you recollect your childhood, are your recollections pleasing to you?
Nick: Number 1, I don't remember how often I used to jerk off, but it was a lot. Number 2, I wasn't pissed off at my dad, even when I was old enough to know what he and mom were doing in the bedroom. Number 3, I don't look in the toilet before I flush it. Number 4, I haven't wet my bed for a long time. Number 5, why don't the two of you go fuck yourselves; I'm outta here.
Gus: I thought you said he was a rock and roll star.
Lt. Walker: He was a retired rock and roll star.
Capt. Talcott: A civic-minded, very respectable rock and roll star.
Gus: What's that over there?
Nick: It looks like some civic-minded, very respectable cocaine to me, Gus.
John Correli: Did you kill Mr Boz, Miss Tramell?
Catherine: I'd have to be pretty stupid to write a book about killing and then kill him the way I described in my book. I'd be announcing myself as the killer. I'm not stupid.
Gus: Did you ever do drugs with Mr. Boz?
Catherine: Sure.
Gus: What kind of drugs?
Catherine: Cocaine. Have you ever fucked on cocaine, Nick? It's nice.
[Catherine Tramell uncrosses her legs and it can be seen she's wearing no underwear]
Nick: You like playing games don't you?
Catherine: I have a degree in psychology, it goes with the turf... Games are fun.
Gus: Well, she got that magna cum laude pussy on her that done fried up your brain!
Internal Affairs Investigator: There's no smoking in this building, Detective.
Nick: [repeating Catherine] What are you going to do? Charge me with smoking?
Nick: Let me ask you something, Rocky, man to man. I think she's the fuck of the century, what do you think?
John Correli: Were you ever engaged in any sadomasochistic activity?
Catherine: Exactly what did you have in mind, Mr. Correli?
Beth Garner: [knocks on the door at Nick's apartment] Nick! Nick, are you there?
Nick: Go away, Beth! I don't want to see you.
Beth Garner: [unlocks the door and enters the apartment, finding Nick drinking] I still have my keys.
Nick: Put 'em on the table and leave.
[pause]
Nick: [shouts] Put 'em on the goddamn table and leave!
Beth Garner: [throws the keys on the floor] Damn it! Don't shut me out, you owe me more than that!
Nick: I don't owe you anything! And you don't owe me anything. We went to bed 10, maybe 15 times. That's miserable enough to carry an obligation.
Beth Garner: Sometimes I really hate you.
Nick: Oh, then why don't you get yourself some friendly little therapist and try to work out all that hostility. Then maybe you can get off once in a while.
Beth Garner: [Nick finds out that Beth and Catherine had slept together in college] What was I supposed to say? "Hey, guys, I'm not gay, but I did fuck your suspect"?
Nick: I'm in love with you already, but I'll nail you anyway.
[Nick just had rough sex with Beth]
Beth Garner: You've never been like that before. Why?
Nick: You tell me, you're the shrink.
Beth Garner: You weren't making love to me!
Nick: Well, who was I making love to?
Beth Garner: You weren't making love at all.
Gus: Where in the fuck you've been? I went over to your place.
Nick: Easy, cowboy, easy. I wasn't there.
Gus: I went over last night, too.
Nick: No, I wasn't there either.
Gus: You fucked her? Goddamn dumb son of a bitch, you fucked her! Goddamn, you are one dumb son of a bitch!
Nick: Next time I'll use the rubber.
Nick: How did you feel when I told you Johnny Boz had died, that day at the beach?
Catherine: I felt somebody had read my book and was playing a game.
Nick: But you didn't hurt.
Catherine: No.
Nick: Because you didn't love him.
Catherine: That's right.
Nick: Even though you were fucking him.
Catherine: You still get the pleasure. Didn't you ever fuck anybody else while you were married, Nick?
Nick: I'm working my ass off, I'm off the sauce, I even stopped smoking.
Beth Garner: How's not smoking?
Nick: It sucks.
Nick: What is this? Some kind of JOKE?
Nick: You wanna play hard, come on!
Gus: I don't buy it! There's gotta be somebody there, who knows whats going on.
Nick: I KNOW WHAT HAPPENED ALRIGHT! Catherine told me and everything she said has checked out!
Gus: You've got Goddamn tweety birds flying around your head! You think the two of you will fuck like minks, raise rugrats, and live happily ever after!
Capt. Talcott: Hey Nick!
Nick: What?
Capt. Talcott: Keep your three o'clock!
Nick: You want me to work the case!
Capt. Talcott: I SAID KEEP IT!
Nick: ALRIGHT! I'll keep it.
Beth Garner: Something's going on. You're sleeping with her, aren't you?
Nick: Why are you interested in her?
Beth Garner: My interest is in you, not her. She seduces and manipulates people. She'll do anything she can.
Nick: I thought you hardly knew her?
Beth Garner: I know the type. I'm a psychologist.
Nick: That means... you manipulate people too! You're a practicing psychologist. You're better at it than she is!
Catherine: Killing isn't like smoking. You can quit.
Catherine: [TV Version] Have you ever had sex on cocaine, Nick?
Dr. McElwaine: You working on another book?
Catherine: Yes, I am.
Gus: It must really be something making stuff up all the time.
Catherine: Yeah, it teaches you to lie.
Nick: [Yells at Marty angrily] Stop bribing me man, I will kick your fucking teeth in!
