A pretty girl is driving through the west. Her car runs out or gas, and
an Indian comes along on a horse, and gives her a ride to a gas station.

Every few minutes he lets out a wild whoop that would curdle milk.

Finally, he drops her off with a final "Yiiieee-yiiieee-yiiiee!" and
gallops off.

"My god!" says the gas station guy. "What were you doing to that Indian
to make him holler like that?"

"Why, nothing," says the girl. "I just sat behind him with my arms
around him, holding onto his saddle horn."

"Lady..." says the guy, "Indians don't use saddles."
