How sexy is Freakonomics?

How sexy is Freakonomics? Not sexy enough for Turkey. Geez. I found this to be too funny.

On a related note, I received my free autographed Freakonomics book plate from Steven Levitt and Stephen Dubner a while back, as I'm sure thousands of others did. Naturally, being a skeptic, I can't help but wonder what the story is behind this give-away. An experiment by the authors perhaps?
If so, I guess we'll find out when the market is fully infiltrated with autographed copies. Apparently some people have a lesser estimate of the popularity of the give-away than I do – a quick check at eBay tells me someone is looking to sell a signed copy outright for $90USD.
