시즌 1, 에피소드 36: Almost as determined as Endora to break up Samantha's marriage to a mere mortal, Samantha's cousin Edgar, an elf, begins playing pranks on Darrin. Darrin's agency has been trying to hold onto the Shelley Shoe account. Edgar, invisible to all, plagues Darrin in his office. Darrin is sure Endora is working on him again, and has difficulty persuading Larry Tate to let him present the new campaign to Mr. Shelley. At the sales meeting, Fred Schulwiler, as unscrupulous competitor, almost gets the account when he makes it appear that Darrin is trying to make Mr. Shelley look ridiculous. When Samantha convinces Edgar that she is very happy with Darrin, he switches his attentions to Schulwiler. Before Edgar is through, Schulwiler has lost all chance of landing the Shelley account. Darrin, coming up with an advertising campaign featuring an elf not unlike Edgar, ties up the account for his firm.
