The Winklevoss twins, who have found Facebook founder Mark Zuckerberg a tough nut to crack, have switched tactics against their arch rival.
In June, twin brothers Cameron and Tyler Winklevoss, who claim Zuckerberg stole their idea for Facebook, appeared to have abandoned legal attempts to renegotiate the original $65m settlement.
But they have not given up taking cheap shots at Zuckerberg, it seems, if their appearance in a television ad is anything to go by.
And what product did the illustrious twins choose to endorse? Is it an online service that is likely to hit Zuckerberg where it hurts most or some high-tech innovation?
No, but in an ad touting Pistachio nuts (off all things), the twins joke about how someone might steal an idea about the best way to crack a nut, in a not too subtle reference to Zuckerberg.
The settlement reached in 2008 was made up of $20m in cash with the balance in shares and is now thought to be worth more than $100m, but the twins claim Zuckerberg defrauded them by overstating the value of the shares when negotiating the settlement.
