Firefly

[Flashback to Serenity's' early days, with a mechanic named Bester, whom Mal catches in flagrante delicto.]

Mal:
Bester - get your prairie harpy off my boat, and put us back in the air.

Bester:
Okay-y, but... can't.

Mal:
What do you mean, "can't"?

Bester:
No can do, Cap. Secondary grav boot's shot.

[Bester's local girlfriend calls out from behind the engine, where she's getting dressed again.]

Kaylee:
No, it ain't! Ain't nothing wrong with your grav boot. Grav boot's just fine. [waves to Mal] Hello!

Bester:
She doesn't... eh, that's not what... [to Kaylee] No it ain't!

Kaylee:
Sure it is! Grav boot ain't your trouble. I seen the trouble plain as day when I was down there on my back before. Your reg couple's bad.

. . .

Mal:
You got much experience with a vessel like this?

Kaylee:
I never even been up in one before.

Mal:
Wanna?

Kaylee:
You mean...

Mal:
Sure.

Kaylee:
For how long?

Mal:
Long as you like. Long as you can keep her in the sky.

Kaylee:
You offerin' me a job?

Bester:
W-w-w—what?

Mal:
Believe I just did.

Kaylee:
[grins] I just gotta ask my folks. [starts to leave, turns back] Don't leave without me! [runs off]

Bester:
Mal! What do you need two mechanics for?

Mal:
[Turning and leaving the engine bay] I really don't.
