In S1E17, Rory is talking to a sleepy Lorelai about possible rewards for the end of their chore-day. Rory says, “Or we could stuff our purses full of sour patch kids and milk duds and go see the Stars Hollow elementary school production of ‘Who’s Afraid of Virginia Woolf?'”
“Who’s Afraid of Virginia Woolf?” is a 1962 play, written by Edward Albee. It follows a dinner party at the home of a middle-aged married couple with their younger married guests. The characters get drunk, flirt with each other, tell stories about a make-believe son, and insult each other mercilessly. It is a definitely not an appropriate play for an elementary school.
