Buying a 'Horth'

This guy owns a horse stud farm, and gets a call from a friend, who tells him, "I know this midget with a bad speech impediment who wants to buy a horse and I'm sending him over".

The midget arrives, and the owner asks if he wants a male or female horse.

"A female horth", the midget replies.

So the owner shows him one.

"Nith looking horth, can I thee her mouf?"

So the owner picks up the midget and shows him the horses mouth.

"Nith mouf, Can I thee her eyeth?"

So the owner picks up the midget and shows him the horses eyes.

"Ok, what about the eerth?"

Now the owner is getting irritated, but he picks up the midget one more time and shows him the ears.

"OK, finally, can I thee her twat?"

With that, the agitated owner picks up the midget and shoves his head up the horse's twat, then pulls him out.

Shaking his head, the midget says, "Perhapth I thould rephrathe that. Can I thee her wun awownd?"
