Bones, Season 8

Booth:
So what do you think? Man or a woman?

Brennan:
I am uncomfortable defining sex with just a skull.

Booth:
Come on. Take a stab. I won't write anything down, I promise. It's between me and you. (Brennan looks at Hodgins) Oh, well...

Hodgins:
What? You don't want to take a stab in front of me?

Brennan:
I feel inhibited by my desire not to embarrass myself in front of another scientist.

Booth:
You should take that as a compliment.

Hodgins:
What about him?

Brennan:
Well we live together and thus share the same synergistic lack of inhibition which allows us to have sex without being self-conscious.

Booth:
That's very romantic, Bones.
