In S1E17, Lorelai tells Luke that Dean broke up with Rory. Luke is angry and starts ranting about how he always knew Dean was no good. Luke says, “Well, forget it! Good riddance, adios, bienvenidos, hasta la vista.” Lorelai responds, “Can we get off the small world ride and get cooking, please?”
“It’s a Small World” is a ride, found in every Disney theme park worldwide, consisting of hundreds of dancing and singing dolls dressed in costumes from various world cultures.
