Slate.com has an interesting essay asserting that North Carolina comedians are redefining American humor. It's a flattering premise, and the author (Evan Smith Rakoff, a Manhattan writer who as far as I can tell,
isn't a closet Tar Heel is from Asheboro and graduated from UNC-Greensboro) makes his point by tracing North Carolina comedy influences from Andy Griffith to David Sedaris and Zach Galifianakis. And it's not just about those guys, who are pretty much household names, but lots and lots of other actors and writers and directors and producers with North Carolina ties who are plenty current and influential.
It's definitely worth checking out.
