Two cowboys came upon an Indian lying on his stomach with his ear to the ground.
One of the cowboys stops and says to the other, "You see that Indian?"
"Yeah," says the other cowboy.
"Look," says the first one, "He's listening to the ground. He can hear things for miles in any direction."
Just then the Indian looks up. "Covered wagon," he says, "About two miles away. Have two horses, one brown, one white. Man, woman, child, furniture in wagon ..."
"Incredible!" says the cowboy to his friend. "This Indian knows how far away they are, how many horses, what color, what's in the wagon -- just amazing!"
The Indian looks up and says, "Ugh ... not amazing ... wagon ran ... over me ... 30 minutes ago!"
