Just before Freakonomics hit the bookshelves, a reporter from the Financial Times named Tim Harford flew out to Chicago to write a profile about me, which you can read here.
At the end of the interview, he asked me to autograph his book. I was surprised because no one had ever asked me to sign anything ever before. But I did it. My first signed book.
Tim recently suggested that we should put the book up for auction at Ebay and give the proceeds to charity, even letting me choose the charity. The charity is Smile Train, which performs corrective surgery on indigent children with cleft lips and palates in China, giving them a second chance at life.
The Ebay listing is here, if you are interested in bidding.
