Tribal Wisdom
So a cowboy is riding along a trail in the old west and sees an Indian lying on his stomach with his ear to the ground. As he gets closer he hears the Indian saying to himself "Wagon...two gray horses...two passengers, man and woman...man driving" The cowboy goes "Wow! you can tell all that by just putting your ear to the ground?" The Indian replies "No. Wagon pass half hour ago, run me over."
