Need some amusement in your life? Call Uncle Arthur, or, in this case, don't call him. Uncle Arthur arrives playing practical jokes on Darrin and Endora while Samantha is trying to get these two antagonists to make up once and for all. After many hits and misses, Darrin needs Uncle Arthur's help in getting Endora back. This is the famous ""Yagazuzie Zim"" episode.

Darrin has a hard time with an eccentric client named Madame Maruska, whom he thinks is Endora. Because of his faulty knowledge, he loses the account. When he learns that Endora did not mess with him, he apologizes to Madame Maruska and still doesn't get the account. It's up to Samantha to win her over using magic.

Samantha hires an English maid named Elspeth, much to the dismay of her previous owner, Montdrake. He is so mad that he does horrible things to Darrin to get her back.
