While Samantha is preparing Tabitha for kindergarten by hiring a warlock tutor, Prof. Phipps. Endora, hoping to help Darrin impress his boss, casts a spell that causes every phrase he speaks to come out as a cliche. The meddlesome mother-in-law mistakenly thinks cliches are an asset to Darrin's advertising career and so he is plagued to saying things like: "A rolling stone gathers no moss"; "tickled pink"; and "what's good for the goose is good for the gander." The problem comes when Larry Tate, Darrin's boss, threatens to cook his goose if he doesn't show more originality in his latest ad campaign for H.B. Summers, head of marketing for Multiple Industries.
