In Episode 1.14, Lorelai's parents state that they never go to Europe in the springtime. However, in 1.19 when Emily meets Michel for the first time, they talk (in French) about the beauty of Paris in the springtime.
Lorelai and Rory spend about a minute mocking the Donna Reed show, while with Dean. Full and partially consumed slices of pizza appear and disappear from their hands. Rory is shown three times taking the first slice of pizza from the box.
When they are watching the Donna Reed show, Dean comes in with pizza and a salad, he pulls out his salad (the container is closed) and when he pulls out the fork, its open and ready to be eaten.
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.
When Taylor and Kirk ask Luke to verify that he is painting and Luke is boxing up leftovers, he adds the napkin and closes the lid twice.
