Introducing Lorelai Planetarium - S7-E8
Visible crew/equipment: While April is wrapping the gift for Sabrina, when Luke talks to her about the party, the reflections of the set's reflector screen and a crew member wearing blue pants are visible on the toaster's silver surface. (00:23:50)
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.
