Brennan and Booth in “The X in the File”

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!
