Rory: They're not going to fire Dean.
Lorelai: Really, why not?
Rory: Well, for starter's, someone stole Taylor's ladder last week and Dean is the only one who can reach the top shelves.
Lorelai: Huh, interesting.
Lorelai: Just as Marty, aka Eve Harrington, shows up trying to take Dean's job, Taylor's ladder mysteriously disappears, suddenly making Dean invaluable no matter what fancy tricks Lon Chaney Junior over there pulls. Good thinking, Dean – smart thinking, my friend.
Rory: You need to start napping in the afternoons.
