Apology Required

A salesman stopped at a local bar for a cold one, and sat down between two older weather-beaten cowboys. On TV, a media celebrity was fawning over 0bamacare. The salesman said to the cowboy on his right, “Man, that 0bama is a real horse’s ass!”
The cowboy stood up and knocked him off his bar-stool and walked out.
The salesman got up, dusted of the sawdust, sat back down and after a few moments silence turned to the cowboy on his left and said, “Man, I ‘m telling you, that 0bama is a real horse’s ass!”
That cowboy got up, knocked the salesman off his stool onto the floor and also walked out.
The salesman finished his beer and asked the bartender, “What’s the matter with those two cowboys? Is this 0bama country?”
The bartender said: “Nope. Horse country.”
