The X-Files, Season 6

Scully:
(from the bathroom) Mulder, speaking of cleaning up, whoever taught you how to squeeze a tube of toothpaste? (Her arm, coming from the bathroom doorway, shows him the tube squeezed in the middle; he ignores it)

Mulder:
Hey, what do we know about this stuff?

Scully:
I'm driving down to San Diego tomorrow and have it analyzed.

Mulder:
All right.

Scully:
Third warning: (sound of toilet seat falling) Toilet seat. (toilet flushes)

Mulder:
(sprawls out on the bed) Why kill Big Mike? (Scully comes out of the bathroom wearing a bright green mud mask; Mulder looks up and is startled) Whoa!

Scully:
What's missing here is intent. What would be the motive? (throws sweatshirt at his head)

Mulder:
Compulsive neatness, or a lack thereof. Have you noticed how everybody around here is obsessed with the neighborhood rules and the CC&Rs? You know what? You fit in really well here.

Scully:
(pointedly looking at him lying on the bed) And you don't.

Mulder:
(adjusting the pillows) Well, anyway, tomorrow I got a, uh, a surefire way of testing out my theory. (pats the bed beside him seductively; waggles his eyebrows at her; she raises her eyebrows; he tries coaxing) Come on, Laura, you know... we're married now.

Scully:
(correcting) Scully, Mulder. Good night.

Mulder:
(gets up and takes a pillow; pauses next to her; looks very serious) The thrill is gone. (Scully sighs)
