Quote from Rory in How Many Kropogs to Cape Cod?
Rory: Grandma and Grandpa invited him to dinner. Lorelai: You're kidding. Rory: It was actually less of an invite and more of a freak-out. They heard about the dinner I went to. Lorelai: Heard how much? Rory: The Reader's Digest version. Lorelai: Got it. Rory: Apparently they've already exceeded the polite reciprocal invite window, and if he doesn't come to dinner soon, Grandma has to give back her pearls.
