A Midwest farmer was describing his lifestyle to a touring group of city folk's. One of the benefit's of this profession, he explained, is that we have built- in weather prediction's." What do you mean by that? asked one inquisitive visitor. When the cow's are standing, the farmer explained, it mean's no rain is likely for the next twenty-four hour's. When they're lying down, it mean's it's going to rain. On our bus trip, another visitor piped in, "I saw half the herd standing and the other half lying down. What does this mean? " The farmer flashed a smile and answered, That mean's half of them are wrong."
