An indian is lying flat on his stomach on the street with his ear held to 
the road.  A man walks by and hears him muttering:
"1972 Ford Mustang, Red with white trim, two passengers"
The guy is really impressed and calls out, "Hey man, this is incredible.
You can tell all of that just by the vibrations on the road."
The indian replies: "No asshole, that's the car that hit me and drove off."
