The real most interesting man in the world doesn’t do commercials for Dos Equis, he is Prince Hubertus von Hohenlohe, famous for competing at the 2014 Sochi Olympics slalom event for Mexico in a Mariachi speed suit.
A little background on Von Hohenlohe, his noble status is somewhat questionable as his royal descendants come from a German kingdom that crumbled over 200 hundred years ago but he chooses to go by the royal title.
