"Bo and Luke ask a group of African-American college students for directions. "Is this a joke? Some kind of reality show?" one of them asks. Bo, the dimmer of the Dukes, explains the flag is cool and that their friend Cooter, a Civil War buff, painted it when he fixed the car. But Luke understands, and explains to Bo that some people find the flag offensive and a 'symbol of slavery.' That Luke, he always was perty' smart."
I think this scene is just injecting humor into the controversy.
I think I'm going to hurl ping.
