Continuity mistake: When Lorelai and Luke are in Luke's Diner to choose the color for the walls, Luke turns around the 'closed'-sign on the door. In this shot the venetian blind at the door is quite messed-up; partly closed, partly opened. In the following shot, where all the people are standing outside Luke's Diner looking through the windows, the venetian blind is orderly and completely opened.
Continuity mistake: In the first scene when Dean brings pizza and they are discussing about Donna Reed: In one shot Lorelai is opening the pizza box and she and Rory take a piece and start eating while they are talking. In the following shot, the piece of pizza in Lorelai's hand is gone and Rory takes a piece from the box - you can see that the pizza is complete again.
Continuity mistake: After Rory is walking with Dean, it goes to a shot of Rory and Lorelai eating at Luke's Diner from outside. Rory is wearing a light blue sweater and Lorelai has a black shirt on. Then it goes inside the diner and Rory is wearing a dark bluish/grey sweater and Lorelai is wearing a purple shirt. The first shot is used from the very last scene of the episode.
Continuity mistake: The Gilmore Mansion is different than in later episodes. The entrance way has steps to go up to the front door landing. In future episodes, the front entrance and driving area are very different. No steps to the front door and the parking area in front keeps changing, adding bushes and a fountain type sculpture.Dennis Sells
Continuity mistake: When Lorelai gives a speech to Dean she says Rory cannot get on his motorcycle, and he responds that he didn't have a motorcycle. During the double date with Lane and Todd Dean says he works only on his bike with Todd, and a few episodes later when Christopher shows up in town Chris and Dean compare their motorcycles.
