If you don't know about the whole Donald/Rosie thing, then here's the Cliff's notes. Donald Trump was nice to Miss America and Rosie O'Donnel called him a "snake oil salesman," which I don't understand. I thought Donald Trump's job was to ride in helicopters and have a stupid-looking haircut.
Anyway then Donald Trump called Rosie a "beast" and threatened to sue her for calling him a "snake oil salesman." What the hell is snake oil, anyway? Anyway this is how people behave who belong to more sophisticated social circles than you.
