The episode opens with Lorelai and Rory playing a word game to determine which of them has to clean out the refrigerator. Each having to pick in turn a disease to match a letter of the alphabet, Lorelai picks “narcolepsy” for the letter N – a callback to the previous episode, when Dean was re-named “Narcolepsy Boy” after falling asleep with Rory at Miss Patty’s. Even though she made peace with Dean and Rory, Lorelai is still not letting this one go.
Later in the episode we see Lorelai cleaning out the refrigerator, so presumably she lost the contest. She may have had to forfeit as a result of rushing over to the pet fair and saying, “Puppies!” on the letter P, instead of a disease.
