Hillary’s Saga Continues

A woman named Hillary 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 then 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," Hillary 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'"
