During the parade, Luke says "This town..." and Lorelai adds" ...is our town, this town is so glamorous", which is a reference to the Go-Go's song 'This Town'.
At the end of the episode Rory tells Lorelei she has home movies from her trip with Emily. She then plays a scene from "A Room With a View" starring Maggie Smith and Helena Bonham Carter.
Lorelai says good morning to a guy named Al. It is suspected that this is Al from Al's Pancake World.
The brick building that Lorelai walks past at the start of the episode (with the sign reading "Lenas Stationary") Is the same building seen in the movie "La La land" as the studio coffee shop where Emma Stone's character works. It is located on the back lot of Warner Bros. studio.
While discussing the brochures displayed at her inn, Lorelai says that she wants to avoid a "We'll leave the light on for you" feel. That is a reference to a TV slogan advertising the low-cost Motel 6 chain, commercials that featured spokesman Tom Bodett delivering that line.
