Brennan: It's a Halloween party. We could be Wonder Woman and -- what's Superman's secret identity?
Booth: Clark Kent.
Brennan: Yes. We could be Wonder Woman and Clark Kent after a really, really bad date.
Booth: Yeah, bad date because you shot me.
Brennan: It was only a flesh wound. And you dropped me on my head.
Booth: After you shot me, okay? I think I got you on this one. Okay, Wonder Woman?

Brennan: It's as if this man spent a great deal of time on his hands while engaging in a repetitive motion.
Wendell: ...I get it!
Brennan: This motion would be reminiscent of a primate having intercourse!
Wendell: We are looking for a horny farmer, yes we are.

Brennan: It's ridiculous to think that there's anything on this planet worth seeing which merits crossing what are literally astronomical distances.
Booth: Maybe aliens are anthropologists. Maybe they just want to study our religion, and sex, and love, and our funny languages and line dancing.
Brennan: That's an interesting possibility I hadn't considered.
Booth: Well they're living creatures. They like to reach out, Bones.
Brennan: Living creatures like to reach out and eat each other.
Booth: Oh, so what are you saying? That the aliens just want to come down here and drink our spinal fluid?
Brennan: Well, if the aliens are advanced enough to fly faster than light, then they can probably make spinal fluid.
Booth: Well you just said that aliens are nice.
Brennan: I did not!
Booth: You just basically said that aliens are nice anthropologists.
Brennan: I don't think so.
Booth: You think that aliens are you!
Brennan: [laughs] You got me! I'm one of them. I was sent down as an advanced scout.
Booth: Ha! I knew it! No probing! No probing!!
Brennan: [laughs] Hey, probing is a valuable way to gather information.
Booth: I know how you people like to probe!

Brennan: Let's pretend we are objective scientists and not indulge in conjecture.

Brennan: Maybe I should start packing heat again.
Booth: Packing heat?
Brennan: Yes, it's a colloquialism. I'm quite a good shot.
Booth: Hey, if the leprechaun was shot, where would the bullet be?
Brennan: I assume somewhere in the six tons of crap Hodgins hasn't sifted through yet.
Booth: Wait, wait a second. Did you just call forensic evidence crap?
Brennan: It's colloquial again. What do you think?
Booth: I like it. It shows that you're adapting.

Brennan: Maybe it wasn't a U.F.O. that Cal saw.
Booth: Ah.
Brennan: He could've seen something else.
Booth: Yeah, like a death beam or a space baby.

Brennan: Megan Shaw is still alive.
Hodgins: What do you want me to do?
Zack: He wants us to guess.
Hodgins: Well, my guess is Hawaii.
Cam: Not Hawaii.
Booth: W-Well, guess again, but better.
Hodgins: Nop, sorry.
Angela: Booth, THEY don't guess.
Booth: Who's they?
Cam and Angela: [pointing at Brennan, Zack and Hodgins] THEM!
Booth: Well, that's just stupid
Zack: We do not guess.
Booth: You know what? You're a horse's ass!
Zack: [referring to his Halloween's costume] Cow! I'm a cow! See my udder?

Brennan: More expertise is required instead of just feet.
Booth: Yeah, gosh. You really are not going to stop until this Canadian foot guy is paralyzed from head to toe.
Brennan: Would you accept an agent who specialized in murders that only occurred in February?
Booth: Okay, that's different.
Brennan: Not to me.

Brennan: Music...Shhh, it's down there. [gesturing]
Booth: That's not music...it's bagpipes.

Brennan: New boyfriend spending a lot of time with your son?
Booth: Yeah. So, you got any new information for me Bones?
Brennan: (referring to Parker) I'm sorry.
Booth: Yeah, there's no need.
Brennan: It must be hard, not being able to see him when you want to.
Booth: See, this is information that I already know, Bones. Why don't you, let's say we just discuss the case, hm?
Brennan: (sees that he's upset) Sure.
Booth:You know, I'm his father. Parker knows that. I mean, that's, that's what's important, not some stupid trip to the zoo.
Brennan: No, absolutely.
Booth: Right.
Brennan: Yeah.
Booth: Done.
Brennan: Of course.
Booth: Boom.

Brennan: No lions?
Hodgins: Not in the whole park.
Booth: There are tigers. How much difference can there be between lion urine and tiger urine?
Brennan: There are no stripes in lion urine.

Brennan: No offence to you, but you're a stodgy traditionalist when it comes to relationships, buddy!
Booth: Stodgy?Stodgy.

Brennan: Not tonight. I have a dinner.
Booth:: What? Wow. I just assumed that the two of you would be eating off an autopsy table.
Brennan: Not tonight!
Booth: I was being...uh...Tomorrow's fine.

Brennan: Now you're a mind reader?
Booth: Maybe. You want me to guess your weight?
Brennan: You do and you could lose a tooth.

Brennan: Observation isn't just seeing Dr. Wyatt, it's experiencing. Ideally, I'd prefer being inside Booth's head. Seeing and feeling things the way he does. Then maybe I'd understand.
Wyatt: Be one with him.
Brennan: In a scientific sense.
