It is close between this one, Rory's Graduation and "The Big One", but I still think this is my favorite episode from Season 3. First, I love when Rory chickens out and Lorelai pretends to be her by putting on that flinty, high voice. Plus when Lorelai was messing around when filling out the Application is great. "Oh my God, what you were doing when the application arrives is worth 50%".
"Mother, breathtaking, Father, Ostrasized!" And the whole Droopy Drawers cracks me up every time!!
I like when Rory and Lorelai are freaking out about getting in. "We all give the same run of the mill perfunctory answers!"
Then the family stuff with the Springsteens is great. There are so many great things about this episode, definitely top 3 of all GG episodes!!
