The Dark Knight

Classic Movie Line, "The Dark Night", The Joker (played by the late great Heath Ledger) barges into the room filled with Mob Bosses. He discusses his plan which bottom line is to destroy Batman. They laugh, and one of the bosses ask, "Why haven't you already killed him". Heath Ledger replies, "If your good at something never do it for free..."

Translation: "If you like what I can do, Show me the money..."
