Double Tate

S2, E23: For his birthday, Endora decides to make three of Darrin's wishes come true. Unaware of the gift, Darrin gets immediate elevator service in his office building, and they sees a bikini--clad beauty. An important client, Randolph Turgeon, insists on seeing Larry Tate, who is in Chicago. Wishing he were Larry for just one day, Darrin immediately turns into his boss. Turgeon introduces Darrin-Larry to his niece, Joyce, who wants a job with the agency.
