The Erlenmeyer Flask

(Scully is holding up an Erlenmeyer flask full of odd-
colored liquid.)
Scully: Ok, Mulder, but I'm warning you. If this is monkey 
        pee, you're on your own.

Scully: Do we even know why the suspect was being chased?
Mulder: As far as I can tell, he wouldn't pull over for a 
        moving violation.
Scully: Well, that ought to put him on the ten most wanted 
        list.

Mulder: You think he does it because he gets off on it?
Scully: No. I think he does it because you do.

Scully: I should know by now to trust your instincts.
Mulder: Why? Nobody else does.

MIB: Your cellular phone has been ringing off the hook.
Mulder: I'm a popular guy. Why don't you answer it for me?
MIB: Oh, I don't like talking on the phone. I have this 
     thing about unsecured lines.
