Are you a Freakonomics fan?

One of the best books that I read last year was Freakonmics by Steven D. Levitt and Stephen J. Dubner and I am definitely a Freakonomics fan. Their thought process was intriguing and made you want to delve into the hows and whys of everyday life and all our myriad tasks. I read the Freakonomics blog on a daily basis and several months ago, asked for an autographed sticker to be sent to me to affix in my book. Since it costs too much to mail books to them and for them to mail the books back, they instead offer an autographed sticker that can be mailed to you. Hmmm, I just looked for the link to get this sticker and it's not on the site anymore....
