Royals run amok.

Our latest Einstein Award goes to Sarah Ferguson, the Duchess of York, who’s been caught on videotape — in a Maxwell Smart caper of her own invention — selling access to her ex-husband, Prince Andrew, for $720,000. An undercover reporter is shown handing her a $40,000 down payment and promising to wire the balance to a private bank account.

Apparently the Duchess currently owes creditors as much as $7 million as she tries to keep up a royal lifestyle she can’t afford, which includes a Bentley limousine and chauffeur, blowing thousands of dollars on handbags, hats and hair accessories, a staff of aids and personal assistants, sponging, haggling, requesting invoices for everything and using her daughters’ credit cards to stay afloat. And if that’s not bad enough, whenever they’re presented with a bill her assistants are trained to look offended and say, “Surely the Duchess isn’t expected to pay for this?”

Oy, Sarah ... this is 2010 ... who turned you into Marie Antoinette? Do you seriously think the rest of us could ever get away with this crap? I mean, can you picture me with a full cart in the checkout lane at Target saying, “Surely Marcy isn’t expected to pay for this?” Or trying to sell somebody secret access to Sam?

I think this woman needs a JOB. And since the Duchess obviously has no vocational training of any kind — or any skill in undercover operations — she might think about driving her own car and selling Amway. Thank you for reading this.
