Jack Rogers

 is a prospective client of McMann & Tate who owns the company, Rogers Party Supplies.

Mr. Rogers and his wife, Phyllis, attend a business dinner at Darrin's and Samantha's house along with Larry and Louise Tate. During the course of the evening, Darrin turns into a werewolf because of Endora's curse. While the Tates and Phyllis are scared of Darrin's disturbing behavior, Rogers thinks Darrin's "costume" is terrific.

As the evening draws to a close, Rogers compliments Endora on her "costume". As he leaves, Endora zaps a lion's tail on him.
