'We thought the U.S. had already hit rock bottom on [the statistical measurement of social progress],' researcher Charlie Ong said during a presentation to government officials. 'But just look at this line graph before and after the data for Mississippi is added. See? Ugh.' Observers noted that if you factor in truck-fixin' and waving from porches, Mississippi still does pretty good for itself.
