The title of this episode refers to a rare ailment which befalls Endora. In his efforts to cure Endora of her allergy, Dr. Bombay inadvertently transfers all of Endora's magical powers to dotty old Aunt Clara. At first delighted that his mother-in-law can no longer plague him with witchcraft, Darrin soon learns to his chagrin that a powerless Endora is even more irritating than her former self. Written by Richard Baer, "Allergic to Macedonian Dodo Birds" (originally the "dodo" was supposed to have been a "road runner") was originally telecast on November 16, 1967. ~ Hal Erickson, Rovi
