Once upon a time, a forest where some pigs lived, caught on fire and all the pigs were roasted. People, who at that time were in the habit of eating raw meat only, tasted the roasted pigs and found them delicious. From that time on, whenever men wanted roasted pork they set a forest on fire. There were men who worked at setting the woods on fire (firemen). There were experts studying the best weather conditions to achieve the best roasted pigs. There were wind specialists who could be trained and become Certified Anemotechnicians. Due to the many bad points of "the system" complaints grew at an increasing rate, as the system expanded to involve more and more people. It was obvious that it should be drastically changed. One day a fireman named John Commonsense said that the problem was really simple and easily solved. Only four steps need to be followed: the chosen pig had to be killed, cleaned, placed in the proper utensil, placed over the fire so that it would be cooked by the effect of the heat and not by the effect of the flames. The director general of roasting after hearing the four point idea said: "What you say is absolutely right, in theory, but it won’t work in practice. What would we do with our weather experts, for instance?" And what shall be done with the forests that are ready to be burned - forests of the right kind of trees needed to produce the right kind of fire, trees that have neither fruit, nor leaves enough for shade, so that they are good only for burning? You are lacking in good judgement, Commonsense! if your plan is adopted, what would I do with such experts as the president of the committee?"
