Having worked for Mr Branson for a number of years, I can just imagine him asking this question. I also remeber the CEO of Virgin Atlantic say in a recent speech that his biggest dilemma when being interviewed for the job in Necker Island was what he should wear! But back in real world of interviews in offices, I think its really important to have a special question that tests candidates ability to think on their feet, and not one that they have prepared for. I quite like this one "If you were sat where I am, what killer question should I be asking you"
