Scully: Mulder, I know what you did wasn't by the book.
Mulder: Tells you a lot about the book, doesn't it?

Scully: Mulder, the hearing is tomorrow at 10 o'clock.
Mulder: So that gives us 24 hours to investigate.
Scully: My assignment is to bring you back, not help you dig yourself in deeper.
Mulder: "The Last Detail" starring Dana Scully.

Scully: Mulder, there are thousands of scientists working on the Human Genome project.
Mulder: Yeah, but only one who decided to go bungee jumping with medical gauze wrapped around his neck.
Season 2

Scully: Must be for the visually impaired.
Mulder: How do you like that? A politically correct elevator.

Scully: Okay, Mulder. But I'm warning you, if this is monkey pee, you're on your own.

Scully: The 65-year-old female teller was pistol-whipped. Died from a massive subdural hemorrhage all because she didn't put the money in the bag fast enough.
Mulder: Lovely couple.

Scully: What are you going to do?
Mulder: I know what I'm not going to do. I'm not going to hang around and wait for Barnett to send me another valentine.

Scully: What do you think?
Mulder: I think I'm going to suggest we sleep with the lights on.

Scully: Who is this "Deep Throat" character? I mean, we don't know anything about him. What his name is, what he does...
Mulder: He's in a delicate position. He has access to information and indiscretion could expose him.
Scully: You don't know that this isn't just a game with him. He's toying with you. Rationing out the facts.
Mulder: You think he does it because he gets off on it?
Scully: No. I think he does it because you do.

Scully: You've got that look on your face, Mulder.
Mulder: What look is that?
Scully: The kind when you've forgotten your keys and you're trying to figure out how to get back in the house.

Scully: Death by hypovolaemia. 75% blood loss. That's over 4 liters of blood.
Mulder: I'd say the man was running on empty.

Scully: From the trucker's description, the shape he fired on could conceivably have been a mountain lion.
Mulder: Conceivably.
Scully: The National Weather Service last night reported atmospheric conditions in this area that were possibly conducive to lightning.
Mulder: Possibly.
Scully: It is feasible that the truck was struck by lightning, creating the electrical failure.
Mulder: It's feasible.
Scully: And you know, there's a marsh over there. The lights the driver saw may have been swamp gas.
Mulder: Swamp gas?
Scully: It's a natural phenonemon in which phospine and methane rising from decaying organic matter ignite, creating globes of blue flame.
Mulder: Happens to me when I eat Dodger Dogs.

Scully: Good sailing, Ahab.
Captain William Scully: Good night, Starbuck.

Scully: I just think it's a good idea not to antagonise local law enforcement.
Mulder: Who, me? I'm Mr. Congeniality.
Scully: You never know, we might need his help one of these days.
Mulder: I'll send him a bundt cake.

Scully: Is this what it takes to climb the ladder, Colton?
Agent Colton: All the way to the top.
Scully: Then I can't wait 'til you fall off and land on your ass.
