The old sherrif was sittin' outside the local saloon one day watching a young cowboy ride into town. When the cowboy got to in front of the saloon he dismounted, tied his horse to the hitchin' post and brushed as much of the dust off him as he could. He then walked behind his horse, lifted it's tail and planted a big, wet kiss right on the horses butt.
As he walked up to the saloon doors the sherrif said, "Now hold it right thar, son. Did I jist see you give yer horse a kiss on it's butt?"
"Yep", the cowboy replied.
"How come?" the sherrif asked.
"My lips are pow'rful chapped," he answered.
The sherrif was curious. "Does thet hep?" he asked.
"Not really," the cowboy replied. "But it keeps me from lickin' 'em".
