Samantha and Darrin flashback to just before Adam was born, whenDarrin has to go to Japan to do business with a client, but cannot leave Samantha's side when her baby is due. Endora breaks Darrin into two people: the fun Darrin and the business Darrin, with strange and hilarious results.

Note: First episode filmed with Dick Sargent; the story is framed as a flashback to when Samantha was expecting Adam.

After learning that "plays on words" helps Darrin in his line of work, Endora casts a spell that makes Darrin speak only in clichés. Whether she meant to pick on Darrin or not, Endora ends up helping Darrin in the end after all.
