Green Eggs and Crack.

Apparently, the Danish didn’t want to go with the U.S.’s apples-and-oranges cover graphic, right, when they published their cracked yolk version, above, of economist Steven Levitt’s and journalist Stephen J. Dubner’s 2005 smash, Freakonomics: A Rogue Economist Explores the Hidden Side of Everything.

Levitt and Dubner’s treatise on the economics of drug dealing, sumo wrestler cheating, and the effects of abortion on crime has sold over 3 million copies to-date. That kind of worldwide success, you think, would move other countries to tow the line, stay with what works, and, from the look of these other versions, most did. Not the Danes, though…or the British, for that matter, who avoided foodstuffs altogether for both the hardcover and paperback versions of the book.

Why? Hopefully Levitt/Dubner will explain it in their upcoming text, SuperFreakonomics. I kid you not.
