Mulder: Tell me I'm crazy.
Scully: Mulder... you're crazy.

Mulder: Tell me, have you done much circus work in your life?
Mr. Nut: And what makes you think I've ever spectated a circus? Much less been enslaved by one?
Mulder: I know that many of the citizens here are former circus hands, and I just thought that...
Mr. Nut: You thought that because I am a person of short stature, that the only career I could procure for myself would be one confined to the so-called 'Big Top'. You took one quick look at me, and decided that you could deduce my entire life. Never would it have occurred to you that a person of my height could have possibly obtained a degree in Hotel Management.
Mulder: I'm sorry. I meant no offence.
Mr. Nut: Well then why should I take offence? Just because it's human nature to make instantaneous judgements of others based solely upon their physical appearances? Why I've done the same thing to you, for example. I've taken in your all-American features, your dour demeanour, your unimaginative necktie design, and concluded that you work for the government; an FBI agent... but do you see the tragedy here? I have mistakenly deduced you to a stereotype. A caricature, instead of regarding you as a specific, unique individual.
Mulder: But I am an FBI agent.

Mulder: The man was obsessed with reincarnation.
Scully: Being obsessed with it doesn't mean you can do it.
Mulder: No. Unless he knew something we don't.
Scully: Like what? The secret password?

Mulder: They told me that even though my deodorant is made for a woman, it's strong enough for a man.

Mulder: Well, that's one of the luxuries of hunting down aliens and genetic mutants. You rarely get to press charges.

Mulder: What if it is a female, Scully? How close is she to you or me? Does she feel emotion? Or are her days just spent looking for food?
Scully: Maybe, she spends her day shopping.
Mulder: Eight million years out of Africa, I don't think we're all that different.
Scully: Mulder, we've put men into space, we've built computers that work faster than the human mind.
Mulder: While we over-populate the world and create new technologies to kill each other with. Maybe we're just beasts with big brains.

Mulder: Who was that on the phone?
Scully: A guy.
Mulder: A guy. Same guy as the guy you had dinner with the other night?
Scully: Same guy.
Mulder: You going to have dinner with him again?
Scully: I don't think so.
Mulder: No interest?
Scully: Not at this time.
Mulder: [walking to the door] What are you doing?
Scully: Going with you to the Smithsonian.
Mulder: Don't you have a life, Scully?
Scully: Keep it up, Mulder, and I'll hurt you like that beast woman.
Mulder: Eight million years out of Africa...
Scully: [holding door open for him] And look who's holding the door.

Mulder: Why would I make them so uncomfortable?
Scully: It probably has to do with your reputation.
Mulder: Reputation? I have a reputation?
Scully: Mulder, look, Colton plays by the book and you don't. They feel your methods, your theories are...
Mulder: Spooky? Do you think I'm spooky?

Mulder: Yeah, did you know that the ancient Egyptians worshipped the scarab beetle and possibly erected the pyramids to honor them, which may be just giant symbolic dung heaps?
Scully: Did you know the inventor of the flush toilet was named Thomas Crapper?

Mulder: Yeah, I had a praying mantis epiphany and, as a result, I screamed. No, not... not a girlie scream, but the scream of someone being confronted by some before unknown monster that had no right existing on the same planet I inhabited. Did you ever notice how a praying mantis' head resembles an alien's head? I mean, the mysteries of the natural world were revealed to me that day, but instead of being astounded, I was... repulsed.
Scully: Mulder... are you sure it wasn't a girlie scream?

Pusher (to A.D. Skinner) Take a walk, Mel Cooley.

Salvatore Matola: They said it'd be like living two lifetimes. At- at first, that's what it was like. Not having to sleep at all made us feel like nothin' could touch us, you know? We'd do 24 hour patrols, night ambushes, you know, and that type of thing.
Mulder: And you never got tired?
Salvatore Matola: No. Not so that we had to sleep. And then, nothing that the pills couldn't fix.
Mulder: Serotonin?
Salvatore Matola: Yeah.
Mulder: How long did this go on?
Salvatore Matola: Quite a while, I'd say. Quite a while - until we stopped taking orders from the company commander in Saigon.
Krycek: You mean the entire squad went AWOL?
Salvatore Matola: Yeah, somethin' like that.
Mulder: Well, then who did you take orders from?
Salvatore Matola: We just made up missions as we went along, until it didn't matter anymore who we were killing. Farmers, women. Outside of Phu Bai, there was this school...they were just kids.

Scully: A few thousand grasshoppers does not constitute a plague.

Scully: According to the briefing, the prisoners escaped while hiding in a laundry cart.
Mulder: I don't think the guards have been watching enough prison movies.

Scully: Apparently miracles don't come cheap.
