I'm seeing double, triple!

THE HANDSOME AND ATHLETIC. You have Bob and Mike Bryan born 4-29-78. They are professional tennis players that plays double. First picture shows their trademark chest bump whenever they win the game. Pics below from timeout.com and bryanbrothers.com.
THE CUTE GONE BAD. Mary Kate and Ashley Olsen born 6-13-86. Both are TV and movie celebrities. They both starred in the sitcom Full House. They were such lovable girls back then but now they are just full of bad publicities. Pics from classicmoviekids.com and drunkreport.com.

THE GOOD NAUGHTY. These are the Visconti triplets Joey, Jason and Jimmy born 2-28-86. They are gay adult entertainers. Let me just say gross to see your sibling naked but there are people fascinated by this. I personally would just be happy seeing one of them in his full glory. :-) Pics from Ragazzi's blogspot and ancientboy's blogspot.
