Christopher: No, we made the movies bad. Think about it. We are the common factor.
Lorelai: Oh.
Christopher: All the movies, very different. Different genres, different languages, even. We saw them in different theaters at different times. What do they all have in common?
Lorelai: They were all seen by us. Wow!
Christopher: Huh?
Lorelai: We can never see Casablanca together. I mean, I'm very sorry. I don't care how much I love it, but I will not be responsible for ruining Casablanca.
