To quote a particularly amusing exchange from the Firefly TV series:
Simon: So, what are we doing?
Kaylee: [looks up] Oh, crime.
Simon: Crime! Good! Okay! Crime.
Kaylee: It’s a train heist. See we fly over the train car, the captain and Zoë sneak in, we lower Jayne onto the car, and they bundle up the booty, and we haul ‘em all back up. Easy as lyin’.
Simon: So you’ve done this before?
Kaylee: [laughs] Oh, hell no.
Kaylee: But I think it’s gonna work.
It makes more sense when you see it:
Sooner or later adventurers are going to end up in the wrong side of the law. Sometimes by choice, or sometimes because the lawmen are just plain rotten. So what should you expect before you end up a criminal?
