A cowboy meets an Indian lying by the side of the road with his ear stuck to the ground. Curious about this Indian custom, he asks what's going on.
The Indian answers: "Big wagon, four wheels, four horses, wagon carry white man, rifle in arms, by side of white man pretty woman, long hair, woman have newborn baby in arms."
Surprised, the cowboy says:
"Gosh Darn! I had heard of the ability of Indians to detect if horses or a wagon were coming only by putting their ear to the ground, but you've surprised me. How is it that you can give so many details just by putting your ear to the ground?"
"It's that it just ran over me!"
