Aunt Clara visits and believes her powers have finally blown a fuse, but in truth, Tabitha is the culprit. Samantha sends Aunt Clara home. Without a baby sitter, the Stephens invite the Tates over to their house. Darrin is convinced the floating objects are the result of Clara's power failure until he pratically catches Tabitha in the act. The Stephens decide to make Larry believe he's had too much to drink in hopes he and Louise will leave before the night is a complete disaster.

The Witches Council orders a coven. Tabitha is being tested for her powers by Hagatha and Enchantra, Endora's sisters who certifies true witches and warlocks. Tabitha passes with flying colors, proving to be an exceptionally talented witch. Hagatha, Enchantra and Endora insist that Samantha enroll Tabitha in a witches' school. After being booby trapped by phone cords and flat tires, Darrin comes home exactly when the decision is made. Darrin, Samantha and Aunt Clara stand against Hagatha, Enchantra and Endora, but Maurice chills the three witches--zapping them to the top of Mount Everest.

Because of a spell placed on a bowl of popcorn by Endora, Darrin becomes a great big couch potato. Samantha finds out what is going on when she finds Darrin, the milkman, and a TV repairman lazing around the messed up house. Samantha calls on Endora to take the spell off of them.

Endora gives Darrin an outstanding memory by hexing his watch, but Darrin learns the hard way that sometimes it is better to forgive and forget.
