Richard in Stars Hollow - S2-E12
Other mistake: Paris was looking to find the seedy side of Stars Hollow. Inside of Luke's she hid behind a menu commenting that she wanted to blend in. She then asked Luke if he gets a lot of truckers. We have all seen the exterior of Luke's and the town square. Paris has walked through it. Where, would a big rig possibly fit or park? Paris is extremely intelligent. She would not have asked the question. Doing so was totally out of character.

Continuity mistake: When Rory and Jess go for the ice cream run the rear-view mirror is missing, but when Rory tells Jess to turn right the rear-view mirror is attached to the windshield in the exterior shot. (00:25:30)
Continuity mistake: When Chris offered to make coffee, and he goes to the water stand, you can see there is already water in the coffee pot.
Chosen answer: Lorelai and Christopher get married impulsively in Paris but they get divorced shortly after returning home. I don't know the exact number of days or weeks but they definitely weren't married for more than a couple of months.
