Well, you've done it!!! You have won 1,000,000 imaginary dollars!!! Now you have to fill out tax forms for the next month and give most of your winnings to the IRS. Every salesman in the country will be trying to sell you something and relatives you didn't even know you had will be dropping in. You'll make more friends in the next two days than you've made in the last century.
