I have decided to add Freakonomics to my list of books everyone in the industry should be required to read.  The list now consists of: (In no particular order)

 

 Money Ball

 America (The Book): A Citizen's Guide to Democracy Inaction

 Freakonomics

 Bringing Down the House

 

Of course, owning both the audio version (from audible.com) and the hard cover first edition of each is probably unnecessary and overly excessive, but admirable.
