Back away from the Amazonian door - this is only one step away ...
KRYTEN: Uh-oh, a door. We'd better use an air vent.
LISTER: No need.
KRYTEN: Sir?
LISTER: Look, I'm gonna do something now, Kryten, that's totally, totally
gross. I don't want you to look. Turn around.
KRYTEN: What?
LISTER: Trust me, you don't wanna know!
...
KRYTEN: Logically, sir, there is only one way you could have possibly
have opened that door. I feel quite nauseous. Where is it?
LISTER: Where's what?
KRYTEN: Oh, sir!! You've got it in your jacket!!
LISTER: I got us out of the hold, didn't I?
KRYTEN: Sir, you are sick! You are a sick, sick person! How can you
possibly even conceive of such an idea?
LISTER: Cheer up! Or I'll beat you to death with the wet end!
KRYTEN: Sir, if mechanoids could barf, I'd be onto my fifth bag by now.
You're a sick person! Sick! Sick!
