It's pretty difficult not to be fascinated by accents. Number one, they're a default, socially acceptable thing to talk about with people you have nothing else to talk about with. Number two, people say pop instead of soda. (“Cause it makes a POP sound when you open the can!”) In that case, will go buy myself a bag of Tostitos weird kissing-like sounds. Yes, I am aware that joke was abhorrent. Blame pop.
Anyway, a great man named Joshua Katz at NC State did an intensive study to chart accents across the nation. We've posted some of the most pertinent/controversial below, but you can view the entire thing here.
