A weird blooper I never really noticed in season 1 episode "The Moving Finger" - Nancy Kovak steps on her skirt when running from Jeannie's indoor rainstorm. She pulls the back waist band waaay down. Given the complexity of filming the rain the production probably decided not to film another take. Or perhaps left in on purpose as it's kind of funny. And it was colorized to shoe her undergarment:
