Bones, Season 5

Booth:
So I have decided to take you up on your offer.

Brennan:
What offer?

Booth:
You invited me to your house for Christmas dinner. You forgot you invited me.

Brennan:
No, it's just -- no! My dad brought by my second cousin and... I really didn't like her.

Booth:
Well that makes sense.

Brennan:
Why do you say that?

Booth:
Because she's family. Ninety percent of the time, family just gets under your skin. That's the difference between family and friends.

Brennan:
She's unapologetically dogmatic, she lives her entire life based on the quotations of Benjamin Franklin.

Booth:
Maybe she feels the same way about you and your mania of logic.

Brennan:
Mania?

Booth:
Okay, enthusiasm.
