The Museum of Natural History held its annual dance last night.

We've done it! We've figured out just what set into motion the financial crisis that has led to billions in losses, demolished two investment banks (so far), and led to tens of thousands of lost jobs. It all goes back to Friday, March 7th when sleazy club owner Simon Hammerstein, headband-wearing scenester Arden Wohl, gay party boy Derek Blasberg, heiress Amanda Hearst, and gala staple Claire Bernard turned up at the New York Stock Exchange to ring the closing bell. Clearly, their mere presence at the exchange unleashed some sort of vicious curse on the markets. Don't believe us? Below you'll find a chart that shows the price of Lehman Brothers since that fateful Friday—or "Black Friday" as the day will henceforth be known—and you'll have all the proof you need that this visit was what doomed the storied firm.

Last week, Columbia MFA student cum socialite Claire Bernard lived a Carrie-Bradshawian fantasy. She got to ring the Nasdaq closing bell! Even better, she got to do so in the company of "writer" Derek Blasberg, who recently blogged about the many burgers he'd eaten during Fashion Week for Jane. We'd never be so crass as to imply that Derek's looking less slender than usual in fashion week's wake, but we do have to single out the Socialite Rank commenter who remarked, "can derek blasberg look more jewish?" Only time will tell, we imagine.

Our feverish excitement about Fash Week has led us to peek into some darker nooks and crannies of the internet than usual; here's a nugget we turned up about socialite Claire Bernard, who mingled with the 'Tinz et al at that One Scottsdale/Vogue Italia party last night.
