I need some help jogging my memory for readily identifiable foursomes. I want to do something fun for a pair of cufflinks which will have to undergo several stages. The first is coming up with either a famous quartet or 4 people that you would associate with each other. They can be an actual quartet like the Beatles or KISS but dont have to be real (Austin Powers/Dr. Evil, Mini-me, Fat bastard), the same sex (Seinfeld, Kramer, Elaine, George) or even from the same time as long you would associate them with each other (Ceasar, Napoleon, Hannibal, Ghengis Khan) they can be serious or comic, they can male (Dean, Sammy, Frankie, Joey) or female groups (Paris, Brittany, Lindsay, Nicole)  all I ask is that they would be recognizable to say a reasonably enlightened crowd. I think the more serious they are the better but maybe not.

And they have to have faces, no helmets, masks etc...
