Harper Valley P.T.A. S02E11 - Svengali of the Valley

When Flora undergoes hypnosis to help her stop eating, the message gets confused and as a result Flora subconsciously reacts to phone bells by treating Stella as her best friend. Meanwhile, Stella is up for a promotion, and her supervisor from Angel Glow cosmetics is in town to get to know her better. The confusion culminates at a crazy dinner party where Flora uncontrollably snaps back and forth between attitudes and almost ruins Stella's business future.
