Lorelai: "Mr. and Mrs. Thomas Lister announce the engagement of their daughter Lindsay Ann to Dean Forrester, son of Randy and Barbara Forrester." My God, they're a good looking couple. If their kids can sing there's no stopping 'em.
Rory: I still don't understand why they need to get married.
Lorelai: Maybe they have to get married before he grows so tall she won't be able to talk to him anymore.
