Visible crew/equipment: Rory interrupts Lorelai and Luke talking at his kitchen table and as Lorelai walks out of the room you can see the boom mic drop in the mirror over Rory's head. (00:19:45)
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.
