EMILY: How did this [Rory’s fractured wrist] happen?
LORELAI: Bees.
An amusing callback to the previous episode, when Lorelai was trying to think of excuses she could use on her parents to explain why Rory was wearing a cast. All she had come up with was, “Really big bees”. Notice that Rory has a cute bee sticker decoration on her cast, the possible inspiration for this ridiculous lie (or the lie inspired the sticker?).
