John Doe: Nothing wrong with a man taking pleasure in his work. I won't deny my own personal desire to turn each sin against the sinner.

George, Library Night Guard: You're going to miss us.

William Somerset: I think I just might!

William Somerset: Gentlemen, gentlemen... All these books, a world of knowledge at your fingertips, and you play poker all night.

Library Guard: We've got culture! We've got culture comin' out our asses!

George, Library Night Guard: [turns on classical music] How's this for culture?

John Doe: [about Tracy to Mills] She begged for her life...

William Somerset: Shut up!

John Doe: She begged for her life and...

William Somerset: Shut up!

John Doe: She begged for her life and the life of the baby inside her.

John Doe: Oh... he didn't know.

William Somerset: [after finding out that Detective Mills's apartment is close to the railway tracks] Just a soothing, relaxing, vibrating home huh?

William Somerset: [recovers] I'm sorry.

Police Captain: You're retiring, six more days and you're all the way gone.

John Doe: I visited your home this morning after you'd left. I tried to play husband. I tried to taste the life of a simple man. It didn't work out, so I took a souvenir... her pretty head.

David Mills: [greeting his wife after coming home from work] Hey, loser.

Tracy Mills: Hi, idiot.

William Somerset: People don't want a hero, they want to eat cheeseburgers, play the lotto and watch television.

David Mills: How much money do we have left?

Photographer: I got your picture man, I got your picture!

David Mills: Oh yeah? Detective Mills, M-I-L-L-S, fuck you!

John Doe: [to Mills] Detective. Detective. DETECTIVE! You're looking for me.

David Mills: Hello?

John Doe: I admire you. I don't know how you found me, but imagine my surprise. I respect you law enforcement agents more everyday.

David Mills: Well, I appreciate that... John. I tell you...

John Doe: No, no, you listen, all right? I'll be readjusting my schedule in light of today's little... setback. I just had to call and express my admiration. Sorry I had to hurt... one of you, but I really didn't have a choice, did I?

David Mills: Hmm.

John Doe: You will accept my apology, won't you? I feel like saying more, but I don't want to ruin the surprise.

William Somerset: We'll just talk to him.

David Mills: Uh huh. Yeah. Excuse me, sir. Are you, by any chance, a serial killer? Okay.

William Somerset: You do the talking. Put that silver tongue of yours to work.

David Mills: Have you been talking to my wife?

California: [to Victor] You got what you deserved.

David Mills: What's in the box?

William Somerset: [discovering what's inside the package] California, tell your people to stay away. Stay away now, don't - don't come in here. Whatever you hear, stay away! John Doe has the upper hand!

William Somerset: [as SWAT prepare to breach and clear] They love this.

Police Captain: [answering phone that interrupted his conversation] This is not even my desk!

David Mills: I seem to remember us knocking on your door.

John Doe: Oh, that's right. And I seem to remember breaking your face.
