Genius idea and redneck engineering seem to go hand in hand quite often. Whether figuring out how to grill with a shopping cart or roll up a window with a drill, a redneck has the solution with common sense engineering. If you see a muffler hanging from the underside of a car with a clothes hanger or a couple of rednecks sitting in a tub outside, with a fire underneath (Redneck Hot tub), you know you are seeing true genius.
