Maude S02E04 "Maude's Facelift: Part 1"

Recently divorced, Maude's friend Vivian decides to get a facelift. Carol and Walter love the "new Vivian" but Maude has nothing but contempt for Vivian's decision. Vivian rightly deems Maude jealous; Maude then makes an appointment to get the procedure done, keeping it secret from Walter.
