Quote from Lorelai in Let the Games Begin
Lorelai: You're seriously gonna run all over town looking for Jess and Rory? Luke: If I have to, yes. And if you were really a concerned mother, you'd go out there with me. Lorelai: No, I can't do that. But if you like, I'll let you sniff Rory's sweater. Maybe her scent will help you track them down. Luke: The things you find amusing astound me sometimes. [grabs Rory's sweater] Lorelai: You're not really gonna sniff it. Luke: No, it's cold out. She might need it.
