Bones, Season 5

[Booth and Brennan are driving to interview a suspect with Booth's grandfather Hank sitting behind.]

Brennan:
Being overweight wasn't always stigmatized. During the Middle Ages in Italy, the wealthy and influential members of society were called popolo grosso, meaning literally, fat people.

Hank:
Is she always like this?

Booth:
You know, Pops, she always has the facts, Pops. Always.

Hank:
You should go on a game show. You'd clean up.

Booth:
I tell her that all the time, but you know, she's already loaded.

Hank:
She's got talent, charm, beauty, money and you're just friends? [Booth looks back at him in bemusement, speechless] I didn't raise you very well.

[Booth and Brennan look at each other awkwardly, still speechless.]
