Sleeping on the Couch in the Living Room

Freakonomics co-author Stephen Dubner was interviewed by CNN's John Sutter. The pair first met when Dubner stayed at his house to sleep on the couch during a World Series game. They began writing free economics in Dubner's office, where they would just talk casually and have fun. "From my perspective as a writer, I couldn't find a way to make it work like that," says Dubner.
