LORELAI: I hate crossword puzzles. They make me feel stupid.
An inside joke. Lauren Graham is very good at crossword puzzles, and would go through several a day on set while waiting for her turn.
Lorelai is looking at a New York Times puzzle book, and judging by the shopping basket Rory is carrying, they are having mac and cheese made from a packet, Twinkies, and a can of Red Bull for dinner that night.
