A young woman from New York City was driving through a remote part of Oklahoma when her car broke down.
An Indian came riding by on horseback and offered to give her a lift to a nearby town. She climbed up behind him on the horse and they rode off.
The ride into town was uneventful except that every few minutes the Indian would let out a loud whoop that echoed back from the surrounding hills.
When they arrived in Bartlesville, he let her off at the local Phillips 66 service station, yelled one final, "Yahoo!" and rode off.
"What did you do to get that Indian so excited?" asked the service station attendant.
"Nothing. I merely sat behind him on the horse, put my arms around his waist and held onto his saddle horn so I wouldn't fall off."
"Lady," the attendant said, "Indians ride bareback."
