Game of Thrones, Season 3

[Tyrion is going through Littlefinger's books of commerce]

Tyrion Lannister:
For years, I've heard Littlefinger is a magician. Whenever the Crown needs money, he rubs his hands together and poof! Mountains of gold.

Bronn:
Let me guess; he's not a magician?

Tyrion Lannister:
No.

Bronn:
He's stealing it?

Tyrion Lannister:
Worse; he's borrowing it.

Bronn:
What's wrong with that?

Tyrion Lannister:
We can't afford to pay it back, that's what wrong with it! The crown owes millions to my father.

Bronn:
Seeing as it's his grandson's arse on the throne, I imagine he'll forgive that.

Tyrion Lannister:
Forgive a debt? My father? For a man of the world, you're strangely naive.

Bronn:
I've never borrowed money before. I'm not clear on the rules.

Tyrion Lannister:
Well...the basic principle is 'I lend you money, and after an agreed upon period of time, you return it...with interest'.

Bronn:
And what if I don't?

Tyrion Lannister:
Well, you have to.

Bronn:
Well, what if I don't?

Tyrion Lannister:
This is why I don't lend you money. Anyway, it's not my father I'm worried about. It's the Iron Bank of Braavos. We owe them tens of millions. If we fail to repay these loans, the Bank will fund our enemies. One way or another, they always get their gold back.
