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.
