1. Gunther IV

It's nice to sound like you're from royalty, but it's best when you fit the part. Gunther III inherited an estimated $372 million from his owner, the German Countess Karlotta Lieberstein. Gunther IV now owns a villa in the Bahamas, a mansion in Miami (the one Madonna used to live in), and he eats caviar and steak. This is probably the first time you envied a dog's life.
