a guy in an expensive car stops by a field where he can see a sheperd with his flock. "Hi Mister Sheperd.I see you have quite a huge flock here.... wanna bet I can tell you how many sheep you have? If I guess the right figure you'll give me one". the sheperd say "OK". the guy gets back in the car, opens his laptop, makes a few satellite phone calls, fills a few excel spreadsheets, then gets out his car and says "you have a 1683 sheep flock!" the sheperd says "that's correct, help yourself". the guy picks a sheep and is about to leave. then the sheperd says: "if I guess what your job is, what would you give me?". and the guy: "I'll give you back your sheep". the sheperd says "Ok. I've no doubt you're a consultant!". "that's correct, but how do you know?" says the guy. "well - answers the sheperd- "first of all, you've showed up where nobody called you, then you had to think about it to tell me something I already knew, and third you don't know shit about my job. and now please give my dog back to me".
