Customer: Hi, I was just wondering if you could tell if cable TV is available at my house. I know it is available in the city, but we are just outside the city limits.
CSR: Yes, we have a very expensive and complicated computer program to figure if there is cable TV available at your address. However, if you answer this one question for me, I can predict the answer 99.9 % of the time.
Customer: Really, what is the question?
CSR: “Can you see cows from your kitchen window?”
Customer: Why, yes I can see cows from my window.
CSR: Well sir, you are going to need a satellite system… There is no cable TV available at your address.
