Californian Bill Helko was thrilled when he had the winning numbers in the local lottery, the first prize being $412,000.

He straight away went and ordered a Porsche, booked a family holiday in Hawaii and had a champagne dinner with his wife and friends at an expensive Hollywood restaurant.

When he went to pick up the winnings he found that 9,097 others had also won first prize and his share of the jackpot was $45.
