To keep the peace, Samantha implores Darrin to be agreeable with Endora when she next visits. He does so, but rather sarcastically. Endora does not like this new view of Darrin, so she, without Samantha or Darrin's knowledge, places a spell on him to make him agree with anything that anyone says. 

Samantha and Darrin are soon off to the Caribbean on what will be their first real vacation in five years, fully expecting Larry to interrupt their attempt at a vacation with a work assignment. 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.
