Gumby, it's a great idea. Would be a lot of fun. But so many folks have posted their pictures; still, there are many who haven't.
To ferret out certain fellows, I would probably look for smug, superior, argumentative, divisive men, and probably wouldn't find them - it might be a situation like happened with the Apostle Paul - he was quite different in person than he appeared in print.
Then I would especially seek you out, and would find a likeable guy in the middle of a crowd, happy, having fun together, all being considered equal as people, no one extolling the exceptional virtues of a very few individuals as if all the others were soooo inferior and not worth bothering with.
Then I would easily identify all the ladies, and have a good time.
