Don't get lost, Null! :P
RIMMER: Yes, but Rimmer Directive 271 states just as clearly, "No chance you metal bastard."
CAT: Come on, man, you gotta sacrifice your life! I'm not asking you to do anything I wouldn't do!
RIMMER: YOU? You'd sacrifice your life for the good of the crew?
CAT: No, I'd sacrifice YOUR life for the good of the crew.
KRYTEN: I beg you to reconsider, Sir. Human history is resplendent with examples of such sacrifice. Remember Captain Oates: "I'm going out for a walk. I may be some time."
RIMMER: Yes, but the thing is, about Captain Oates; the thing you have to remember about Captain Oates; Captain Oates ... Captain Oates was a prat. If that'd been me, I'd've stayed in the tent, whacked Scott over the head with a frozen husky, and then eaten him.
LISTER: You would too, wouldn't you?
RIMMER: History, Lister, is written by the winners. How do we know that Oates went out for this legendary walk? From the only surviving document: Scott's diary. And he's hardly likely to have written down, "February the First, bludgeoned Oates to death while he slept, then scoffed him along with the last packet of instant mash." How's that going to look when he gets rescued, eh? No, much better to say, "Oates made the supreme sacrifice," while you're dabbing up his gravy with the last piece of crusty bread.
LISTER: You've got no magnificence in your soul, have you, Rimmer?
RIMMER: Let's just say we can eliminate the switch-off option.
