Bones, Season 6

Brennan:
[knocks on Booth's apartment door] Booth? [knocks again] Are you there?

Booth:
No, I'm in South Beach working on my tan. [opens door]

Brennan:
You need Sweets to sign your post Afghanistan fitness for duty report. Did you forget?

Booth:
Me?

Brennan:
Well, generally you wear more clothing, and you've been avoiding this for weeks.

Booth:
Well, I couldn't sleep. Hannah got up at the crack of dawn. [cracks back]

Brennan:
Do you always have this pronounced release of gas in the morning?

Booth:
Is it that bad?

Brennan:
Synovial gas. That's what the cracking is.

Booth:
Synovial gas? What's that mean?

Brennan:
Well, there comes a point where your body can't hide all the abuse it's taken.

Booth:
What do you mean 'certain point'?

Brennan:
Booth, you've been shot and beaten and jumped out of airplanes. The skeletal damage alone --

Booth:
Oh, God. I'm falling apart.

Brennan:
You're fine. It's your skeleton that's falling apart.
