Bones, Season 5

Cam:
Were you aware that JFK had scarlet fever in childhood?

Brennan:
Hodgins informed me of that fact, yes.

Cam:
Scarlet fever can cause osteomyelitis.

Brennan:
It's very rare, Cam. It can happen in approximately one in a hundred cases. It's statistically unlikely that it was Kennedy.

Cam:
You're a good person. I will never forget what you did for him.

[...]

Booth:
[offers Brennan his arm before crossing the street] Shall we?

Brennan:
[smiling] We shall.

Booth:
You know, you must think I'm crazy for being so happy that it wasn't JFK.

Brennan:
I'm very impressed. You wanted the truth, even if it was going to hurt you.

Booth:
I learned that from you.

Brennan:
Really?

Booth:
Yeah. I mean, sometimes you have to go with your brain over your gut.

Brennan:
That's nice, but I prefer that you always go with your brain over your gut, because your gut cannot think.

Booth:
Your brain can't digest a breakfast burrito. I'm just saying, to each their own!

Brennan:
To each their own.
