While it may be hard to believe, there really were redneck jokes before Jeff Foxworthy. Rednecks have been around forever. They even have their own Riviera, the Redneck Riviera, which is the Florida Panhandle. And thats no joke. Redneck jokes are always funny because they use a favorite theme of humor
naivety and stupidity. We all know someone who is a bit of a redneck, such as the guy who still refers to his pocket knife as Exhibit A or the guy whose first wife and first cousin share the same name and birthday. What a coincidence!
