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 and canyon walls.

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

round his waist, and held onto the saddle horn so I wouldn't fall off."

"Lady," the attendant said,

Indians don't use saddles."

Good one.
