Mulder: [about seeing a shuttle launch from the control room] I have to admit, that fulfilled one of my boyhood fantasies.
Scully: Yeah, it ranks right up there with getting a pony and learning how to braid my own hair.

Mulder: [in response to some suggestive remarks about Scully] You know, Frohike, it's men like you that give perversion a bad name.

Mulder: [Mr. X hands Mulder an envelope] What's this?
Mr. X: Data from a top secret military project. Born of the idea that sleep was the soldier's greatest enemy.
Mulder: Grissom was conducting sleep deprivation experiments on Parris Island?
Mr. X: Not deprivation. Eradication.
Mulder: Why?
Mr. X: Why else? To build a better soldier. Sustained wakefulness dulls fear, heightens aggression. Science had just put a man on the moon. So now they looked to science to win a losing war.
Mulder: And Willig and Cole were the lab rats.
Mr. X: Lab rats with the highest kill ratio in the Marine Corps. Four thousand-plus confirmed kills for a thirteen-man squad.
Mulder: You think Cole's behind what's happening now?
Mr. X: I'm not here to do your thinking, Agent Mulder. All I know is, that Augustus Cole hasn't slept in twenty-four years.

Mulder: Can you at least accept the possibility that during his near-death experience some kind of psychic transference occurred?
Scully: Can't you accept the possibility that this isn't an X-File?

Mulder: Come on in.
Scully: What are you watching?
Mulder: Something that just came in the mail.
Scully: That's not your usual brand of entertainment... What is it?
Mulder: According to the magazine ad I answered, it's an alien autopsy. Guaranteed authentic.
Scully: You spent money for this?
Mulder: Twenty-nine ninety-five ..... plus shipping.
Scully: Mulder, this is even hokier than the one they aired on the Fox network, you can't even see what they're operating on!
Mulder: But it does look authentic, I mean the settings, the procedures. I mean it does look as if an actual autopsy is being prepared, doesn't it?
Scully: Well, technically, I don't know why they would be wearing gas masks.
Mulder: Well, maybe it's because of this green substance they seem to be extracting from the subject. Can you identify that?
Scully: Olive oil? Snake oil? I suppose you think it's alien blood?
Mulder: It's widely held that aliens don't have blood, Scully.
Scully: I guess this begs the question; if this is an alien autopsy...
Mulder: - where's the alien. But what so intriguing to me is the striking lack of detail here.
Scully: Well, what do you expect for $29.95?

Mulder: Do you believe he's predisposed to this type of psychotic episode?
Scully: I believe it's a long way from saying Jack had a near death experience to saying his body's been inhabited by Warren Dupre. A long way.

Mulder: Don't you want to keep it?
Margaret Scully: When you find her, give it to her.

Mulder: Fear. It's the oldest tool of power. If you're distracted by the fear of those around you, it keeps you from seeing the actions of those above.

Mulder: He believes the government is out to get him.
Mr. X: It's tax season - so do most Americans.

Mulder: Hey, Scully. Do you believe in the afterlife?
Scully: I'd settle for a life in this one.
Mulder: Have you ever seen the Liberty Bell?
Scully: Yes.
Mulder: You know, I've been to Philadelphia a hundred times and I've never seen it.
Scully: You're not missing much. It's just a big bell with a big crack, and you have to wait in a long line.
Mulder: Yeah, but I'd really like to go.
Scully: Why now?
Mulder: I don't know. How late do you think they stay open?

Mulder: I brought you a present. It's a video. Superstars of the Superbowls.
Scully: I knew there was a reason to live.

Mulder: I don't believe you.
Deep Throat: There are limits to my knowledge, Mr. Mulder.

Mulder: I feel, Scully... that you believe... you're not ready to go. And you've always had the strength of your beliefs. I don't know if my being here... will help bring you back. But I'm here.

Mulder: I think I saw some of these same people at Woodstock.
Scully: Mulder, you weren't at Woodstock.
Mulder: I saw the movie!

Mulder: I would never lie. I willfully participated in a campaign of misinformation.
