One of the wordy duo's favorite topics, which comes compliments of their roots (Kentucky for Barnette and southern Missouri for Barrett), is regionalisms, or words and sayings that spring up in a town, state, or region and that leave visitors from elsewhere scratching their heads and trying to figure out what the locals are talking about. "When we look at the origins of words, [we see] that people are endlessly creative and often exuberant with their language and with inventing words and adopting words from the people around them," says Barnette. "I think you see that a whole lot with regionalisms. There's something really delicious about being able to take not a walking tour of America but a talking tour."
