YAAA-HOOOOO!
A pretty girl is driving through the West when her car runs out of gas. Along comes an Indian 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 “Yaaaa-Hooooo!” and gallops off.
“My God!” says the gas station attendant, “What the hell were you doing 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 attendant, “Indians don’t use saddles.”
