Maybe they do. I think they also marry blondes, but turnabout was fair play when someone thought "Gentelmen Marry Brunettes" could succeed as well as "Gentlemen Prefer Blondes".
The sequel to the movie that was made from the book that was made (I think) into a play, then a movie, then a musical, then a movie musical, then probably something else.
The (prequel) book made a pretty penny for the author for all this, which was pretty good for something she dashed off as a joke for a friend.
This (sequel) book was the story of the wisecracking best friend in the prequel.
Anyway, I'm saying all this about everything but the movie because I've never seen the movie....
