Moving into middle age, Darrin begins to notice those human physical imperfections in himself associated with aging. Despite Samantha's assertions that Darrin isn't vain, Endora believes otherwise. As such, she, without Samantha or Darrin's knowledge, places a spell on him to make him vain, more specifically in a youthful manner.

On a lark but also on the urging of her mother-in-law, Samantha enters a slogan contest, the first prize which is a trip for two to Tahiti. A surprised Samantha wins the contest. What she is unaware of is that the company for which she submitted the winning slogan is a client of Darrin's.
