Giddy Up

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 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," 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."
