Steven Dubner & Steven Levitt authors of "Freakanomics" dropped by to talk about their new book "When To Rob A Bank...and 131 More Warped Suggestions and Well-Intended Rants." Over the past decade, Steven D. Levitt and Stephen J. Dubner have published more than 8,000 blog posts on Freakonomics.com. But now they've gone through and picked the best of the best for their new book. You'll discover what people lie about, and why; the best way to cut gun deaths; why it might be time for a sex tax; and, yes, when to rob a bank. (Short answer: never) They also ask: Why don't flight attendants get tipped? If you were a terrorist, how would you attack? And why does KFC always run out of fried chicken?
