"The Girl Who Never Had a Birthday" was the show's first two part storyline (followed by three more, plus the famous four parter), in which Jeannie begins to vanish, her powers weakening, because she is unhappy not knowing when her birthday is (she'd already given a date of July 1, 21 B.C, in the first season entry "G.I. Jeannie"). Meanwhile, Majors Nelson and Healet are assigned to work with ERIC (Electronic Rapid Input Computer), a $500 million super computer that can figure out any problem it is given. Tony comes up with the idea of using ERIC to discover when Jeannie was born, since all she knows is that on that day 2000 years ago Neptune was in Scorpio. Roger's reluctance stems from the fact that if they get caught it's bound to be a suicide mission. ERIC produces the date but all Tony gets is the year 64 B.C. before Dr. Bellows confiscates the strip of paper. By the episode's end Jeannie has lost all her powers and is trapped in a drawer in Major Nelson's desk, with Dr. Bellows ready to move in.
