US Soldier was given the job of hunting for buffalo meat. Needing help, he hired an Indian Scout. The two of them rode off on their journey to find buffalo. After riding a while, the Indian gets off his horse, puts his ear to the ground and says "Humm, buffalo come".
Carefully, the soldier scans the horizon with his binoculars, but sees nothing. Confused he says to the Indian, "I do not see anything, how do you know buffalo come?"
Indian replies, "Ear full of buffalo crap!".
