Luke: "No, not unless you can alter time, speed up the harvest or teleport me off this rock."
C-3PO: "I don't think so, sir. I'm only a droid and not very knowledgeable about such things, not on this planet, anyway. As a matter of fact, I'm not even sure which planet I'm on."
Luke: "Well, if there's a bright center to the universe, you're on the planet that it's farthest from."
