Firstly, there were much better Bo Derek films to see, if your father was into her for birthday suit related reasons. Secondly, I'm not sure how old you were, but I'd have opted for a Disney film instead if I'd been your father. Thirdly, random story: There used to be a BBC daytime TV quiz show called "Going for Gold". I have a random episode of the presenter, Henry Kelly, one day whittling down the final contestants so the final two were "Bo" and "Derek". It got a big laugh.
