Darren: Do you know which French city famous for its water was the capital of collaborationist France?
Lorelai: Oh, me? Um, Evian, Perrier, uh, Le Crystal Geyser?
Darren: Jennifer, you wanna help Lorelai out?
Jennifer: Vichy.
Darren: That's correct.
Lorelai: Oh, that's right. Vichy water, I knew that.
Darren: What about the year of Germany's victory in the Franco-Prussian War?
Lorelai: Huh, me again?
Darren: If you wish.
Lorelai: I don't know that one. I do know Istanbul is Constantinople, so if you've got a date in Constantinople, she'll be waiting in Istanbul.
