A woman from New York was driving through a remote part of Arizona when her car broke down. An American Indian on horseback came along and offered her a ride to a nearby town.
She climbed up behind him on the horse and they rode off. The ride was uneventful, except that every few minutes the Indian would let out a "Ye-e-e-e-ha-a-a-a!" so loud that it echoed from the surrounding hills.
When they arrived in town, he let her off at the local service station, yelled one final "Ye-e-e-e ha-a-a-a!" 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 the saddle horn so I wouldn't fall off," the woman answered. "Lady," the attendant said, "Indians don't use saddles."
