Brennan: People make stupid, irrational decisions.
Booth: They act from the heart sometimes Bones, it's not a crime.

Hodgins: So, these are from the notebook found in our victim's windbreaker?
Angela: Blueprints, schematics, sketches.
Hodgins: "Automatic toilet scrubber." Huh. Like those little vacuum cleaners that move around on their own.
Angela: Things in a toilet bowl should not move.

Brennan: It is nice to meet you Jarhead. I can see the family resemblance. Your facial structure is, even more symmetrical than Booth's.
Jared: Is she coming on to me?
Booth: No it's just the way she talks.

Brennan: Are you thinking of leaving lesbianism behind?
Angela: I prefer not to be labeled, okay?

Jared: (about Booth) He doesn't like to be visible above the ridge line, so he keeps his head low. Instinct. Me on the other hand, well, I cannot help but run that ridge.
Brennan: Can you give me an example? (Jared kisses Brennan)
Jared: I bet you Seeley never took that risk.
Brennan: (smiling) Nope.

Brennan: (toasting Booth) Anthropology teaches us that the alpha male is the man wearing the crown, displaying the most colorful plumage and the shiniest baubles. He stands out from the others. But I now think that anthropology may have it wrong. In working with Booth, I've come to realize that the quiet man, the invisible man, the man who's always there for friends and family... that's a real alpha male. And I promise my eyes will never be caught by those shiny baubles again.

The Scotland Yard mascot Booth got in London during "Yanks in the U.K." is seen on his desk at his FBI office.
