Dear freinds,
here is another nontechnical story which could (nevertheless) have a little bit of truth.
Best wishes Otto
*************************************************************************
A shepherd is supervising his large group of sheeps in a deserted environment. All of a sudden a well-dressed young man comes driving a modern minivan and asks: "If I can find out the number of your sheeps... can I then get one of them"? The shepherd agrees. Thereafter, the young man opens the NASA Internet homepage, scans the environment using GPS satellite navigation system, opens a data base and sixty EXCEL pages. He prints a 150 page report using a very fashionable printer and, finally, he says: "You are owner of exactly 1586 sheeps". The shepherd replies: "That's absolutely correct. Please select one of them for your tonight's meal". The young man selects a sheep and puts it into his minivan. Just before he is starting the motor, the shepherd says: "If I can find out your profession... can I then get my sheep back?". The young man agrees. The shepherd says: "You are a consultant. I'm absolutely sure about that". The young man is stupefied and says: "That's correct. But how could you find out my profession"?
The shepherd: "I have at least three convincing reasons for that: 1. You came without being asked". 2. With a very complicated procedure you have found out something which was already well-known to me. 3. You don't have any knowledge about your customer, (i.e. about my profession) since the sheep which you have selected is the sheepdog."
