Scully: So, how do I die?
Clyde Bruckman: You don't

Scully: So, what are we supposed to charge him with, 'assaulting a cellular phone'?

Scully (to Mulder): Please explain to me the scientific nature of the "whammy".

Scully: How are you feeling?
Skinner: Like someone's been inside my stomach redecorating.

Scully: I'm not going to ask you if you just said what I think you just said, because I know it's what you just said.

Scully: Look, we've been working together for what two years now, we have differing opinions, but I didn't expect you to ditch me.
Mulder: I didn't ditch you.
Scully: Fine, whatever.

Scully: Maybe you're just seeing what you wanted to see.
Mulder: What makes you think I'd want to see that?

Scully: Sure, fine, whatever.
About Mulder not telling Scully he was going to follow up a lead with Detective White.

Scully: Woman gets lonely. Sometimes she can't wait around for her man to be reincarnated.

Scully: [Watching Dr. Berenbaum and Ivanov walking away] Well, think of it this way, Mulder. By the time there's another invasion of artificially-intelligent, dung-eating robotic probes from outer space, maybe their uber-children will have devised a way to save our planet.
Mulder: You know, I never thought I'd say this to you, Scully... but you smell bad.

The Cigarette Smoking Man: What is this?
Skinner: This is where you pucker up and kiss my ass!
The Cigarette Smoking Man: Listen -
Skinner: (Interrupting) Now, you listen to me, you son of a bitch! This man's name is Albert Hosteen. You should remember that. Because if Agents Mulder and Scully come down with so much as a case of the flu, Albert is prepared to recite, chapter and verse, file for file, everything on your precious tape.
The Cigarette Smoking Man: It's a nice try, Skinner.
Skinner: I'm sure you're thinking Albert is an old man and there are plenty of ways you might kill him too. Which is why, in the ancient oral tradition of his people, he's told twenty other men the information on those files. So unless you kill every Navajo living in four states... that information is available with a simple phone call. (Smirks) Welcome to the wonderful world of high technology

Well Manicured Man: We predict the future. And the best way to predict it, is to invent it.

William Mulder: Hello, son. I did not dare hope to see you so soon, nor ever again hope to broker fate with a life to which I gave life. The lies I told you were a pox and poison to my soul, and now you are here because of them. Lies I thought might bury forever a truth I could not live with. I stand here ashamed of the choices I made so long ago when you were just a boy. You are the memory, Fox. It lives in you. If you were to die now, the truth will die. And only the lies survive us.

[Scully and Mulder both reach for the latex gloves]
Mulder: Go ahead.
Scully: No, you go ahead.
Mulder: No, no, no. Be my guest. I know how much you like snapping on the latex.
