O, hai! Had no idea that you, 23-year-old Facebook founder Mark Zuckerberg, were on the list of Forbes' richest people. But your net worth is... $1.5 bil? Forbes helpfully lists which of the men on its Rich List are bachelors. But don't get too excited: the thing about the rich is that they tend to be squirrely. And they'll make you sign a prenup, which is always a total bitch. Forbes has a slideshow of the billionaire bachelors, and as they saying goes: the odds are good, but the goods are odd. [Forbes]
