That's as close to making sense as I get...
Trying to figure you out really does a number on my brain sometimes, Null. ;)
HOLLY: I've just finished reading everything. I've now read everything that's been written by anyone ever.
LISTER: Would you go away?
HOLLY: You know what the worst book ever written by anyone ever was?
LISTER: I don't care!
HOLLY: "Football, It's a Funny Old Game" by Kevin Keegan.
LISTER: Holly, would you let me watch the film?
The film reappears on the screen. HOLLY reappears on the screen, interrupting the movie.
HOLLY: I'm at a loose end now. I don't know what to do with meself.
LISTER: Holly, why don't you just read everything all over again.
HOLLY: I was thinking it might help pass the time if I created a perfectly functioning replica of a woman, capable of independent decision-making and abstract thought and absolutely undetectable from the real thing.
LISTER: (Sitting up eagerly) Well why don't you, then?
HOLLY: Because I don't know how. I wouldn't even know how to make the nose. Heh.
LISTER: Holly, is there something that you want?
HOLLY: Well, only if you're not busy. Would you mind erasing some of my memory banks?
LISTER: What for?
HOLLY: Well, if you erase all the Agatha Christie novels from my memory bank, I can read 'em again tonight.
LISTER: How do I do it?
HOLLY: Just type, "HolMem. Password override. The novels Christie, Agatha." Then press erase.
LISTER jabs two-fingered on a keyboard.
LISTER: I've done it.
HOLLY: Done what?
LISTER: Erased Agatha Christie.
HOLLY: Who's she, then?
LISTER: Holly, you just asked me to erase all Agatha Christie novels from your memory.
HOLLY: Why should I do that? I've never heard of her.
LISTER: You've never heard of her because I've just erased her from your smegging memory.
HOLLY: What'd you do that for?
LISTER: You asked me to!
HOLLY: When?
LISTER: Just now!
HOLLY: I don't remember this.
LISTER: Oh, I'm going to bed. This is gonna go on all night.
