I am a heavy user of Twitter. http://twitter.com/kencarr (or @kencarr if you're on Twitter already).
I Tweeted a week ago "Bought @azlottery Mega Millions tickets. If I win, I'm buying new socks. The reeeal fluffy kind."
Today in the mail I got a box from the Arizona Lottery. They had seen my Tweet and sent me a few scratchers, a Powerball ticket for this Saturday's drawing, and.... SOCKS!
