The world has a new richest man, according to Forbes. But chances are you wouldn't know if Carlos Slim, valued at $53.5 billion, stepped into the room. He doesn't have his own television show, fashion line or personal sneaker. He does have a stranglehold on Mexico's telecommunications industry. For that, we give him a sarcastic "hooray!" After the jump are the billionaires you do know. They're not quite as rich as Slim, but they're a whole lot more sexy (yeah, we're looking at you Mark Zuckerberg)...
