I woke up one morning to find I was famous. I bought a white Rolls-Royce and drove down Sunset Boulevard wearing dark specs and a white suit waving like the Queen Mum.

Over the past 50 years we got versions of X-ray specs and space vacations and even death rays. But the X-ray specs don't fit on your face - they're big things that screen your luggage for guns. Space vacations are real but they cost $20 million. We have death rays but you have to be a triple Ph.D. to play with them.
