This morning, Facebook CEO and hoodie aficionado Mark Zuckerberg changed the world for the second time when he rang the bell, making his multi-billion-dollar company officially public. As Mike Cassidy from the Mercury News so aptly put it: It was like “Christmas, New Year's, Diwali, Tet, Fiestas Patrias and the Fourth of July all rolled into one.”

Investors, the media, and pretty much the whole world were in a Facebook frenzy this morning as they watched the Silicon Valley social media business make a new mark as the biggest tech company IPO ever. More than 100 million shares were sold in under five minutes, which brings us to the next obvious question: How many new hoodies can Mark Zuckerberg buy now that he's worth $20 billion more?

We did some quick calculations and found that an elegant American Apparel hoodie costs $48 — not including tax. Let's assume they let the sales tax slide for Zuck. He could easily take home 416,666,666 brand-new hoodies.
