PCs always seem to be able to hold detailed discussions of their plans, despite being in situations where coherent speech, or speech of any sort, should be impossible. And all the NPCs can do is look on in bemusement.
Obi-Wan: Poison gas? I hold my breath.
Qui-Gon: Me too. I look for an exit.
GM: The gas fills the room, obscuring your vision.
Qui-Gon: Right, I'm gonna kill the butler robot.
GM: No, you can't see it.
Qui-Gon: I swing my sword where it was just standing.
GM: Very well. You miss.
Obi-Wan: This is getting us nowhere.
Qui-Gon: We should get our ship to blast us free.
Obi-Wan: You mean our ship that almost certainly just exploded?
Qui-Gon: Is that what it was? Okay, let's take over this ship.
GM: Are you still holding your breaths?
Both: Of course!
