 " Fear of Flying " was directed by Mark Kirkland , and written by David Sacks . The story of the episode came about when Sacks came into the writers ' room with an idea for an episode where Marge goes to a therapist " for one reason or another " . Sacks and the other writers then structured the rest of the plot around that storyline . Anne Bancroft was called in to voice Zweig . Before Bancroft recorded her part , the animators based Zweig 's design on a <unk> track from cast member <unk> <unk> as the therapist . After Bancroft had recorded her part , Zweig was redesigned to fit with Bancroft 's voice . They added split glasses and a streak of silver in her hair to give her a more mature look .
