Once upon a time, a Chinese arms merchant stopped by a village to sell his wares. He was proudly proclaiming his finest sword made and all of it's virtues. "This sword will penetrate through the strongest armor and the heaviest of shields." he said.
A young peasant hearing his claims stepped up and asked him if he sold any shields. Being a peasant, he was never trained with the sword but believed a good shield would protect him. "Here I have the finest shield ever made" said the merchant and went on to proclaim on how fine a shield it is. "This shield is of such high quality that no sword or arrow will be able to penetrate it."
The peasant paused and then asked him, "what of that sword you were just trying to sell that can penetrate any armor or shield?" The merchant stood there for a moment and finally said, "I am sorry but I must leave to go to the next village."
The more things change, the more they stay the same.
