Vincent: Our foamy friend seems to be petrifying right before our very eyes.

Vincent: The slowest meteorites travel at 25,000 miles per hour.
Hodgins: Uh-huh.
Vincent: I'm not just spouting useless facts. You do not have a chance at recreating those velocities with a glorified blow-gun. You simply want to fire a cannon at a dummy.
Hodgins: [holds out safety goggles] Are you staying or going?
Vincent: Another set of eyes taking note can never be amiss.

Voiceover: People say you only live once. But people are as wrong about that as they are about everything. On the darkest moment before dawn, a woman returns to her bed. What life is she living? Is the same life this woman was living half an hour ago? A day ago? A year ago? [cuts to Booth] Who is this man? Do they lead separate lives or is it a single life shared? ... A storm approaches. It is still over the horizon, but there is lightning in the air. Are either of them aware of the gathering turbulence? Can they feel the crackle of electricity in the wind or are they aware of only the power they generate between themselves?

Voiceover:You love someone, you open yourself up to suffering, and that's the sad truth. Maybe they'll break your heart, maybe you'll break their heart and never be able to look at yourself in the same way. Those are the risks. You see two people and you think they belong together, but nothing happens. The thought of losing so much control over personal happiness is unbearable. That's the burden. Like wings, they have weight, we feel that weight on our backs, but they are a burden that lifts us. Burdens that allow us to fly.
Season 5

Wendell: What happened to your measuring tape?
Brennan: I don't know. Missing. There was a Post-It note from the Egyptology Department.

Wexler: Inspector Pritchard, meet Dr. Brennan.
Pritchaard: Charming
Wexler: She's exactly like me.
Pritchaard: Charming, tenacious, salacious, sophomoric, euphoric, noble, ignoble, fatuous, horrid, morbid, torpid and tedious.
Wexler: Flattery will get you absolutely nowhere, Cate. So you found Portia Frampton?
Pritchaard: Well, the way we usually work, Ian, is I drag the bodies out of the Thames and you use your extraordinary capabilities to identify them.
Booth: Bones! They're like the English version of me and you.

Wyatt: May I say, Dr. Sweets, that this is probably the best work I have ever read on the dynamics of opposite personality types working towards a common cause.
Sweets: Okay, now I'm hearing a caveat.
Gordon Wyatt: Just a small one. It's just that Brennan and Booth aren't in any way opposites.
Sweets: Wow. Small? What is that, British understatement?
Wyatt: Yes, he's a man. She's a woman. He's instinctual. She's empirical.
Sweets: Opposites.
Wyatt: Superficial ephemera, Dr. Sweets.
Sweets: Wow. Okay, what about the sexual component in their relationship? Would you agree that they have both sublimated their attraction to each other out of fear of endangering their working relationship, because their working relationship is paramount to both of them?
Wyatt: Alas, I'm afraid I wouldn't agree with that. No.
Sweets: Wow. Which part?
Wyatt: Well everything you just said. Yes, one of them is acutely aware of their attraction. Struggles with it daily, as a matter of fact.
Sweets: Wow. I'm sorry I keep saying that. Which one?
Wyatt: It's your book, Dr. Sweets. I would never tell you what to write.

Wyatt: Might I offer a word of advice regarding young Dr. Sweets?
Booth: Might I try to stop you.
Brennan: Why do we need advice about Sweets?
Booth: We don't. Sweets is just fine.
Wyatt: He most definitely is not fine. I've read his book.
Brennan: Wait, did he say something mean about us?
Wyatt: On the contrary. You might as well know that he lost both his adoptive parents just before he came to work for your de facto crime fighting unit.
Booth: What are we, the land of misfit toys?
Wyatt: He's a good lad, Sweets, but this book he's writing, he's using it as the vehicle to get what he actually wants. Which is a family.
Brennan: So he imprinted on us like a baby duck?

Zack: I'm king of the loony bin!
Hodgins: Yeah, you are.

[Angela calls Brennan's phone; her voicemail answers.]
Brennan: Hi. Technically you have not reached Temperance Brennan; but if you leave a message, it will reach her. Me. Temperance Brennan.

[Booth and Brennan walk in on a baby shower being held in the multi-purpose room of a high school]
Booth: You have got to be kidding me. Didn't this school ever hear of sex education?
Brennan: Well if so there's gaps in the curriculum.
Booth: That's for sure.

[Booth has taken a lot of Vicodin for his back pain.]
Perotta: How are you, Agent Booth?
Booth: The only reason that I am not coming in right now is because Bones told me not to, but she's your responsibility. Nothing can happen to her, okay? If anything happens to her and all that silky black hair, all that soft skin --
Perotta: I will not let her out of my sight. You have my word. Now we should really get back to the case, Agent Booth.
Booth: Am I stopping you? [hangs up]
Perotta: Right. I'm going to round up as many black knights as I can at Imagicon. In the mean time, please don't go out in the field without me.
Brennan: I don't need a sitter. Booth gets needlessly protective sometimes. I have no idea why.
Perotta: You really don't, do you?
Brennan: No.

[Booth is alone at the sperm bank when Stewie Griffin from Family Guy appears on a TV]
Stewie: Why are you here at the bank, Booth?
Booth: [startled] AH!
Stewie: You've got a hot doctor friend. Go to her and make a direct deposit like a man!
[Booth turns off the TV]
Booth: [to himself] That's impossible.
[The TV suddenly turns itself back on]
Stewie: And yet we converse.
Booth: [Yelps and backs himself up against a wall]
Stewie: [looking at some magazines on a table] Ooh, look! A pile of porn! Delicious! Give me a peek, Booth. Mmm? Just a little peek at a booby? Please?
[Booth unplugs the television and the screen goes black again. As he turns around, the TV turns itself on again.]
Stewie: What's your problem? You're threatened by a cute, harmless baby? Grow a set! You do want her to have your baby, don't you?
Booth: Of course I do, it's just... I want her to have a baby because it's what she wants.
Stewie: And you could just walk away like a heartless cad while she changes poo all by her lonesome?
Booth: It's what she wants!
Nurse: [speaking from outside the room] Are you okay in there, Mr. Booth?
Booth: Uh, I'm fine. Just, uh, fine, thank you. [to Stewie] Listen, could you just go away now, okay? I don't need your help.
Stewie: You know, you're not a bad looking fellow, and if you'd just keep an open mind...
Booth: Go back to cartoon land, wherever you came from. Leave!
Stewie: You sure? I'm good at pretend games.
[Booth uses the remote control to turn the TV off.]
Booth: [Shakes his head] That wasn't possible.

[Booth tries to get out of the Mini Cooper.]
Booth: Ahh! Getting out of this thing is like being born!

[Booth visits Brennan in the first-class section of the plane.]
Booth: Are you tired of working with me?
Brennan: No, it's not that. But the identification and analysis of ancient remains, that's why I became a forensic anthropologist.
Booth: You're bored. The spark is gone.
Brennan: I'm a scientist first.
Booth: Right. Yeah. A scientist first. I get it. I understand.
Brennan: Hey, if you get caught up here, does that make me an accessory?
Booth: [smiles] An accessory to an upgrade.
