I remember years ago watching an interview with Sherwood Schwartz, the creator of Gilligan’s Island, where he talked about his constant battles with network censors. He was given strict rules about Ginger’s cleavage and Mary Ann’s belly button, but Tina Louise would constantly undo the top button on her blouse just before the camera started rolling on a scene.
He said something along the lines of “Between Dawn’s navel and Tina’s tits, I never had a moment’s peace.”
