Not many dudes can say they were literally the most watched and talked about person on Earth for two summers. Michael Phelps is one of them. His record 22 Olympic medals have lent to him being called the greatest Olympian ever.. How could he be so great and still be on this list you ask? Try watching an interview with Phelps and get anything out of it you couldn't get reading his Wikipedia page. For a guy who has supreme talent, Phelps just doesn't the personality you look for in a primetime athlete. His Subway commercials are about as entertaining as a Bobcats preseason game.
