That is absolutely hi-larious. Beautifully written satire. One thing, without trying to sound critical, is it Bobby Ray or Billy Ray? You call him each in different places.
I think you can make up your own "nom du redneck" by combining Wayne, Lee and Ray in any combination. "Wayne Lee Ray" or "Ray Wayne Lee" or such. For variety, throw in an occasional "Bobby." (Warning - This is also an all-purpose death-row inmate name builder).
