Also, if you don't at least tear up while watching this, I highly suggest watching the entire series from start to finish again. At least all the Lorelai story lines. If you really can't bring yourself to watch Rory/Dean/Jess/Dean/Logan again, I understand.
But make sure you don't skip Luke. Or Miss Patty. Or Andrew. Or Sookie (as if). Or Babette. Or Lulu. Or Taylor. Or Paris (again, as if).
