Ms. Backlinie is the swimmer in the opening scene who becomes the first victim of the shark in Jaws (1975). She later spoofed this scene in Spielberg's 1941 (1979) but encounters a Japanese submarine instead of a toothy fish.
I'm not a women's libber. Having a pretty girl running down the beach, then having her torn apart by a shark, is a lot better than having a flabby guy running down the beach and getting torn up. I don't think women are exploited as much as some women think they are.
