Pick any woman on the street. Ask her to introduce you to whom she considers the most beautiful of her friends. Repeat until you get to the 12th woman.
A Japanese television show went to Italy to try it out. I don't agree that the final lady was the prettiest ... but, let's face it, I'd have been happy with the first one :-).
Personally, I think the approach is flawed. I would suggest that many people ... and not just women! ..., asked to nominate their most cosmetically appealing friend would prefer not to show themselves up.
Anyway, here's the process in action, along with some horrible music and ridiculous histrionics from the presenter ...
