The Big Bang Theory, Season 2

Sheldon:
[knock-knock-knock] Leonard! [knock-knock-knock] Leonard! [knock-knock-knock] Leonard!

Leonard:
What Sheldon? What Sheldon? What Sheldon?

Sheldon:
Tell me what you see here. [points to his laptop screen]

Leonard:
The blunt instrument that will be the focus of my murder trial?

Sheldon:
This is Stephanie's Facebook page. Now where it should say "in a relationship", what does it say?

Leonard:
Stephanie Barnett is single.

Sheldon:
Furthermore, earlier this evening, she threw a digital sheep at some guy named Mike. Who's Mike? Why does he get a digital sheep and not you?

Leonard:
It's just her Facebook page! And we've only been going out a couple of weeks.

Sheldon:
You don't see it, do you? We're losing her.

Leonard:
Okay, I'm going to make this very simple for you. You are not in this relationship. I am! Ergo, you have noooo say in anything that happens between me and Stephanie.

Sheldon:
I'm afraid I can't allow that. Pursuant to Starfleet General Order 104, Section A, you are deemed unfit, and I hereby relieve you of your command.

Leonard:
General Order 104, Section A does not apply in this situation.

Sheldon:
Give me one good reason why not.

Leonard:
Because this is not Star Trek!
