Saddles

A pretty girl is driving through the American West when her car runs out of gas. An Indian comes past and gives her a ride to a gas station, sitting behind him on his pony. Every few minutes as they ride along, he lets out a wild whooping yell that echoes around the hills. Finally, he drops her off with a last, “Yaa-Hoo!”
“My god,” says the gas station owner, “what were you doing to that Indian to make him shout like that?”
“Nothing,” says the girl,”I just sat behind him with arms around his sides, holding onto his saddle horn.”
“Miss,” says the man, “Indians don’t use saddles.”
