Blame Booze and Melville - S5-E21
Visible crew/equipment: When Sookie and Jackson rush out of their house because Sookie's in labor, just as Rory tells Lorelai that they should have thrown the baby shower earlier, we can see the reflection of the boom pole and microphone on the hood of the van. (00:12:35)
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.
