Tyrion: Let me give you some advice bastard. Never forget what you are. The rest of the world will not. Wear it like armor, and it can never be used to hurt you.
Jon: What the hell do you know about being a bastard?
Tyrion: All dwarfs are bastards in their father's eyes.
Jaime: Tell me you're not thinking of taking The Black.
Tyrion: And go celibate? The whores would go begging from Casterly Rock. I just want to stand on the edge and piss off the end of the world.
