A man on a horse rides up to a bar, dismounts, lifts the tail of the horse, and kisses its ass.

The man then walks into the bar and has a drink, and meanwhile, everybody is staring at him. He asks the bartender, "Why's everybody staring?"

The bartender replies, "Why'd you kiss your horse's ass?"

"I have chapped lips," replies the man.

"And kissing a horse's ass cures chapped lips?" asks the bartender.

"No, but it sure as fuck keeps me from licking my lips!"
