Quote from Lorelai in I Solemnly Swear
Lorelai: Where you going? Luke: Oh, well, I'm going to Doose's because we are out of food. Lorelai: How can you be out of food? Luke: Well, it starts with the words, "Hey Jess, you do the ordering this week, okay?" and it ends with me selling Kirk a lettuce sandwich. Rory: We've eaten those.
