A stranger rides into town. He ties up in front of the sheriffs office and goes round to the back of his horse which has just relieved itself. The stranger lifts a handful of mess and puts it round his lips.
Horrified, the sheriff runs out.
"Say, boy. What in tarnation do you think you're doing?"
"I got myself a mighty bad case of chapped lips, sherriff," says the stranger.
"And does that help cure it?"
"No - but it sure keeps ya from lickin' 'em!"
