Quote from Lorelai in Take the Deviled Eggs...
Lorelai: And what is with that name... G.G.? Rory: It's a cute name. Lorelai: It is, 'cause she's copying me there, too. Rory, G.G. Rory, G.G. They're identical. Rory: They are not identical. Lorelai: Two syllables, repeating consonants. Rory... G.G. Rory: Oprah, Uma. Lorelai: Don't mock. Rory: I'm just trying to joke you down off that ledge.
