On a hot, dusty day a cowboy rode into a small frontier town. After dismounting, he walked behind his horse, lifted it's tail and kissed it where the sun don't shine. An old man rocking by the general store witnessed the whole thing.
"Whudd'ya do that fer?" he asked.
"Got chapped lips," the cowboy replied.
The old man asked, "Does that help?"
The cowboy said, "Nope, but it keeps me from lickin' 'em."
