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 you can see that 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 trough the windows, the venetian blind is orderly and completely opened.
Other mistake: When Rory returns from being stranded overnight in Hartford, she comes up the walk and meets Lorelei on the porch. Although it's snowing significantly in the background, there is not a single flake of snow on Rory's hair, jacket, or backpack, and her hair is completely dry.
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.
Other mistake: Rory asks Emily for baby pictures of Lorelai, but Emily says Lorelai burned them all because she had such a big head when she was little. But in "Love and War and Snow" earlier in the season, Emily, Richard and Rory looked at a baby picture of Loralie in a bunch of petticoats the night Rory stayed over with her grandparents during a snowstorm.
Factual error: Lane wants Rory to talk to Dean about setting up Lane with his friend Todd. While asking Rory to do this, Lane asks for the date to be planned for the following Sunday, after church; however, Lane is Seventh-day Adventist and they believe the Sabbath is Saturday and therefore attend church on Saturday, not Sunday.
Continuity mistake: Luke uses a red screwdriver trying to get something out of the toaster and leaves the screwdriver in the toaster while he goes to get coffee. When it cuts back to Lorelai, the screwdriver is on the counter, beside the toaster.
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.

Other mistake: When Rory and Lane get caught at the movies, Lorelei said she will not lie to Mrs. Kim because she has to respect that Mrs. Kim doesn't want Lane to do something. In reality, Lane is allowed to do things Mrs. Kim would not approve of all the time i.e. Listening to ungodly music, eating pizza, wearing different clothes.

Visible crew/equipment: While Lorelai and Luke are in the diner's storeroom, just as Lorelai makes a comment about not knowing what's going on in Rachel's head because she's not a Vulcan, the boom mic dips into view over Lorelai's head, at the top of the screen.
Factual error: The morning after Dean and Rory fall asleep at Miss Patty's, when Patty wakes them up, she tells them it's five-thirty in the morning. When Rory runs out into the street, there is snow on the ground and the sun in up. In Connecticut, there is no time of year in which there would be both snow on the ground and sunlight at 5:30 a.m. (It's not streetlights either-in other episodes that take place at night in the town square, the streetlights do not light up the entire square-they are some distance apart, and their light is concentrated around the poles).
