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.
