JAKE: Come on, Nog.
JAKE: Why not?
NOG: It's my money, Jake. If you want to bid at the auction, use your own money.
JAKE: I'm human, I don't have any money.
NOG: It's not my fault that your species decided to abandon currency-based economics in favour of some philosophy of self-enhancement.
JAKE: Hey, watch it. There's nothing wrong with our philosophy. We work to better ourselves and the rest of humanity.
NOG: What does that mean exactly?
JAKE: It means. It means we don't need money.
NOG: Well if you don't need money, then you certainly don't need mine.
JAKE: How much latinum do you have? How much?
NOG: Five bars.
JAKE: Five bars!
NOG: Look, it's taken me a lifetime to save up that much money, and I'm not going to just throw it away for some baseball card.
JAKE: Not even for my father, the man who made it possible for you to enter Starfleet Academy.
NOG: Oh no, that's not fair.
JAKE: The man who believed in you when no one else would.
NOG: Oh, this is so low.
JAKE: I can't believe you would rather keep your filthy money locked away in a box under a bed than use it to give him endless moments of happiness.
NOG: Argh! All right, all right. I'll do it.
JAKE: That's very generous, Nog. I'm proud of you. Now let's get that money.
Nog was winning that argument completely and utterly: if you don't need money, then you don't need mine. End of story. And I would add, if your father is only out to better himself, to gain nothing but self-improvement, then he doesn't need a baseball card.
But the writers set aside all credibility and had Nog surrender his life savings to a manipulative parasite. Nog should never
have revealed how much money he has to that pathetic mooch, to say nothing of handing it over.
