The frontier doc was approached by a young indian, who had just ridden in from the reservation.

"Many moons, chief no shit"

The doctor contemplated this, and produced some laxitive for the chief to relieve his constepation.

"Tell the chief to take one cup every hour. Come tell me when the chief has had a movement"

The next week the same young indian was in his office, so the doctor asked the young man "has the chief moved yet?"

"Chief no move, no move!"

"Tell the chief to take two cups of this every hour."

Two weeks went by, but the young man appeared at the fort, and the doc asked him "has the chief moved yet?"

"Chief moved yesterday, teepee full of shit."
