Luke: Why don't you just change the porch light?
Lorelai: Have you seen how dirty it is up there? With those creepy moths that fly in your face, and you could swallow one, and end up with some weird hand-to-mouth-to-moth disease.
Luke: There's no such thing.
Lorelai: Oh, no? Did you see Mothman Prophecies?
Luke: Yes.
Lorelai: Oh, well, okay then. Did you see the sequel?
Luke: There's a sequel?
Lorelai: Yes. It is a heartbreaking saga in which Richard Gere gets a life threatening disease from changing a dirty porch light.
Luke: There was no sequel.
Lorelai: Well, it's still really gross up there.
