An Australian couple won nearly $500,000 in a lottery jackpot ... by accident. Apparently they thought they were buying a ticket for one game, but bought a ticket for a different game instead. That mistake was worth $453,135.59 "Can you believe I was actually meant to buy a ticket into another draw? This was actually the wrong ticket," the man said. "It was a complete mistake, a very good mistake."Ya think?(UPI)
