Lorelai: How do you know Jess's writing?
Rory: Oh, well, I lent him a book, and he wrote some stuff in it.
Lorelai: He vandalized one of your books?
Rory: No, he didn't vandalize it, he wrote in the margins, thoughts and stuff.
Lorelai: What, like, "play basketball, eat a sandwich", stuff like that?
Rory: No, like margin stuff. People like Mark Twain wrote in margins.
Lorelai: "Pilot a steamboat, write Huckleberry Finn".
