I just finished the book Irrationally Yours: On Missing Socks, Pickup Lines, and Other Existential Puzzles by Dan Ariely. You may have heard of or read some of Ariely's other books, such as Predictably Irrational: The Hidden Forces That Shape Our Decisions or The Honest Truth About Dishonesty: How We Lie to Everyone--Especially Ourselves.
This latest book is a compilation of mostly questions and answers that he has posted in the Wall Street Journal, about everything from financial advisors to investing to social networks to decision making to just about everything else you can think of.
Ariely inserts a lot of humor throughout the book. I especially like the recommended suggestion he posted at the end of the chapter on choosing a wine at a restaurant. The chapter on choosing a plane flight, called "On Riding Your Dryer to Tucson", was hilarious. The choosing the best bathroom stall was great also.
By the way, each chapter is one page long, so this is a very easy read. Great for plane flights, beaches, and poolsides.
I highly recommend you get a copy of Irrationally Yours for your education, enlightenment, and entertainment.
