One day in Dodge city a cowboy rides into town. He pulls up outside the saloon and gets off his horse. He ties the horse up and then walks round the back of it, lifts the tail and kisses the horses backside with puckered lips. He then walks into the saloon.

Across the street an old timer cant believe what hes just seen so he rushes across and bursts into the saloon where he sees the cowboy drinking at the bar.

Hey mister, he says. Did I just see you kiss that hoss ass?

Yep.

If you dont mind me askin. Why dya do that?

Cos I got chapped lips, replies the cowboy.

And kissin your hoss ass cures chapped lips?

Nope, says the cowboy, but it sure stops you lickin them.
