To help him, he hired a Native American scout.
The two of them set off on their journey to find buffalo.
After riding awhile, the scout gets off his horse, puts his ear to the ground and says “Hmmm, buffalo come.”
The soldier scans the area with his binoculars, but sees nothing.
He is confused and says to the scout, “I do not see anything, how do you know buffalo come?”
The scout replies, “Ear sticky”.
