As a birthday present, Endora grants three wishes to Darrin; the only trouble is, she fails to inform Darrin. Later on, the hero expresses the wish to be "just like" his boss Larry Tate. In an instant, Darrin is transformed into Larry's exact lookalike -- and that's only the beginning, folks. Adding to the confusion is a bikinied beauty named Joyce (Kathy Francis), and an impatient client named Turgeon (Irwin Charone). Written by Paul Wayne, "Double Tate" was first telecast on February 17, 1966.
