Jayne: There’s times I think you don’t take me seriously. I think that ought to change.

Mal: Do you think it’s likely to?

Jayne: You got something you don’t deserve.

Mal: And it’s brought me a galaxy of fun, I’m here to tell ya.

Jayne: Six men came to kill me one time. The best of ’em carried this. It’s a Callahan full-bore autolock. Customized trigger, double-cartridge thorough gauge… It is my very favorite gun. (holds it out to Mal)

Mal: …Dàxiàng bàozhà shì de lādùzi (“The explosive diarrhea of an elephant”), you offering me a trade?!

Jayne: A trade?! Hell, it’s theft. It’s the best damn gun made by man. It has extreme sentimental value. It’s miles more worthy than what you got.

Mal: What I got? She has a name.

Jayne: So does this. I call it Vera.

Mal: Well my days of not taking you seriously are certainly coming to a middle.
