Lorelai: "Tomorrow I'm going to build a house."
Rory: Help build a house.
Lorelai: Did you tell them there's a light bulb in your closet that burned out in '97 you still haven't changed?
Rory: It's for charity.
Lorelai: Don't those people have enough problems without having you as a contractor?
Rory: I'm sure there will be real construction workers there. I will be assisting and helping out those less fortunate than myself. I will be getting college credit, and this is the end of this conversation.
Lorelai: You're right, it's a good thing. Nice. Keeps your halo shiny.
