Bobby becomes obsessed with Jesse James. Mike and Carol don't approve of his new hero, and try to find a way to convince him that James was nothing but a "mean, dirty killer."

After a chimp follows Samantha and Tabitha home, Samantha turns him into a man to find out where he belongs. Harry, the former chimp, insists on living a man's life for just one day. At Darrin's office, Evelyn Tucker, and her assistant, Bobby Flynn, are searching for an ad symbol for Brawn, a new man's cologne. When Larry tries to stall until Darrin returns from Canada, Evelyn insists on waiting for him at the Stephens' home. Fascinated by Harry's simian antics, Evelyn decides he would be a perfect model for Brawn. Samantha declares that Harry must leave until Larry warns if Harry isn't in his office next morning, Darrin is out of a job. Samantha worries when Darrin phones he'll be away another two days. After posing all morning, Harry decides being a man is no fun. Larry phones that Harry's photos are great and plans a national tour for him. Harry, however, insists on becoming a chimp at once until Samantha advises him. After Harry turns the studio upside down and reduces Evelyn to hysterics, she fires him. Samantha applauds, explaining Harry was just launching Darrin's campaign for Brawn, based on the wild emotions it arouses. Evelyn feels it's sensational and Larry takes all the credit. Back with his owner, Samantha is sure the chimp will leave again.

Although Samantha is calm, collected and waiting with suitcase in hand to go to the hospital to give birth, it is Darrin who is having complications of the nervous type. Darrin's dilemma is further complicated by Samantha's eerie father, Maurice, who is ready to play grandpa even before his daughter delivers. Another nervous father-to-be, Ralph Davis, is somewhat embittered when, after his six-hour vigil, Darrin's baby arrives first.

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.
