They Shoot Gilmores, Don't They? - S3-E7
Continuity mistake: When Luke fixes Lorelai's shoe, he squeezes glue onto the broken heel and places the glue bottle down on the seat to his left, then he holds the heel to the shoe with both hands, but in the next shot that glue bottle is suddenly back in Luke's hand while he's still holding the heel to the shoe.

Continuity mistake: During the dance marathon while Luke is fixing Lorelai's shoe, Taylor can be seen on the podium in the background changing from standing to sleeping over and over.
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.
