    Yeah a was 3rd place winner too. A won 8.75 million. And a new car and he gave me a number to call it was 4063184572 and he got all furious with me when I told him I refused to give him my address. And i didn't believe any of this, he would stop and 'try' and cover the phone speak amazing English then when he came back to me he nearly spoke English. They really don't have anything better to do. Really?
