Bones, Season 4

Brennan:
Cam says that everybody thinks I'm a cold fish.

Booth:
What you are is Iceland: cool to the touch, but underneath you're all volcano!

Brennan:
I don't like people thinking that I'm a cold fish.

Booth:
Look, if you were really a cold fish, you wouldn't care.

Brennan:
You used logic on me! That's sweet! [They smile.] Cam says the reason I didn't hear the gunshot is because I'm cheating on you.

Booth:
Oh, Jared thinks, you know, I'm the killer, and he's helping me get away with it.

Brennan:
So you're a murderer; I'm unfaithful. We are a very exciting couple!
