Battlestar Galactica, Season 1

Adama:
Madame President, we are the proud owners of the universe's first bona fide Cylon detector.

Roslin:
Well, that is great news. So... when do we begin?

Adama:
Doctor Baltar would like to start widespread testing as soon as possible, but there are some serious limitations, because he can only do one person at a time and verification takes hours.

Roslin:
So, who's going to go first?

Adama:
[thinking for a second] The test... right. I think people in sensitive positions should go first.

Roslin:
I completely agree. How about you?

Adama:
Excuse me?

Roslin:
If you're a Cylon, I'd like to know.

Adama:
If I'm a Cylon, you're really screwed. [Adama and Roslin both start laughing.]

Roslin:
Seriously, I do think you should go first. Show everyone in the fleet that they can trust the people at the top.

Adama:
Well then, maybe YOU should go first. [silence] All right... I'll go first.
