CAT and LISTER are lying on bunks in a darkened room, watching television.
LISTER: Cat?
CAT: Mmm?
LISTER: Ya ever see the Flintstones?
CAT: Sure!
LISTER: D’ya think Wilma’s sexy?
CAT: Wilma Flintstone?
LISTER: Maybe we’ve been alone in deep space too long, but every time I see that sharmi body, it drives me crazy. Is it me?
CAT: Well, I think in all probability, Wilma Flintstone is the most desirable woman that ever lived.
LISTER: That’s good. I thought I was goin’ strange.
CAT: She’s incredible!
LISTER: What d’ya think of Betty?
CAT: Betty Rubble? (Pause) Well, I would go with Betty... but I’d be thinking of Wilma.
LISTER: This is crazy. Why are we talking about going to bed with Wilma Flintstone?
CAT: You’re right. We’re nuts. This is an insane conversation.
LISTER: She’ll never leave Fred, and we know it.
CAT shakes his head in resignation.
That is perhaps the funniest bit on a show with hundreds of goood bits. The punchline slays me every time.
