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-h-a-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-h-a-a-a-a!" and rode off.

"What did you do to get that Indian so excited?" asked the
service-station attendant.

"Nothing," the woman answered. "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."

"Lady," the attendant said, "Indians don't use saddles."
