Yeee Haaa!!!!

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."
