Brennan: Why do you think your father needs a girlfriend so much?
Booth: (whispering to Brennan) Okay, Bones, there's a whole gender-pairing dealie-bob thing going on here. You're just going to confuse him.
Parker: So I can have a pool.

Parker: Hi Dr. Saroyan. Do you have a boyfriend?
Angela: (to Booth) See, this is exactly how it started with me.
Booth: Come on let's go. Come on, I gotta get you back home or your mom's gonna kill me, alright? Let me see this stuff. (tries to rub the paint off Parker's face) Does this stuff come off?
Angela: Oh seriously, that's your big worry right now?

Booth: You seriously believe all that hoo-hah?
Brennan: Well, it's anthropology, so yes.
Sweets: Wrong-ology. Keep your grubby anthro-hands off my psych.

Sweets: Parker is transitioning from latent, to genital. At the genital stage, he's learning to identify with his gender parent -- that's you. He's looking at you to see his sexual future.
Booth: How do I get him to stop?
Sweets: My advice is to let him see you interact with a woman.
Booth: Easy.
Sweets: No, not sexually, socially. Show him you're comfortable with women, so he can learn to be the same way.
Booth: Okay.
Sweets: Okay. Just like that? You're taking my advice?
Booth: No, I just don't want to talk to you about it anymore.
