Not to mention since it is that high they will sell about 3 or 4 of the same ticket. (There are only about 30million combinations, so if you have that much money when it gets that high just buy 30 million unique tickets and you are garenteed to win.)
This happens quite often to have 4 or 5 winners when the pay out gets that high. It just brings out more fools. (Thus in many circle the lottery is call a tax on fools.)
