A Redneck Comback

Two businessmen in Birmingham, Alabama are sitting in their soon-to-be new store...as yet, the store isn't ready - only a few shelves are set up.
One says to the other, "I bet any minute now some redneck is going to walk by, put his face to the window and ask what we're selling."
No sooner were the words out of his mouth when, sure enough, a curious redneck walks to the window, has a peek and asks, "What y'all sellin' here?"
One of the men, being a smartass, replies, "Oh! We're selling assholes here."
Without skipping a beat, the redneck says, "Well, I see y'all are doing really good, you only got two left!"
