In S1E18, Lorelai is teasing Emily for giving her a present that had initially been a gift from Richard’s mother to Emily. Lorelai says, “What would Miss Manners say about this?” Emily replies, “If she met your grandmother, she’d understand.”
Miss Manners is the pen name used by Judith Martin. She writes a column, carried by hundreds of newspapers, about the rules, history, and theory of etiquette. She began “Miss Manners” in 1978 and received a National Humanities Medal in 2005 for her work.
