Former Gov. Kathleen Sebelius took some heat several years ago for saying that the quality of the roads in Missouri was scary. Now Missouri Gov. Jay Nixon has poked fun at the intelligence of Kansans. When asked this week whether an expansion of the University of Missouri-Kansas City Dental School could end up training dentists for Kansas, Nixon dismissed the notion that some graduates might want to practice in Kansas. "But it's so obvious when you cross the state line," Nixon said as the 100 or so in the audience laughed and applauded, the Kansas City Star reported. "People just start talking slower."
