"The horse rancher" joke

A guy calls a buddy, who is a horse rancher, and says he's sending a friend over to look at a horse.
The horse rancher asks "How will I recognize him?"
That's easy, he's a midget with a speech impediment."
The midget goes there, and the rancher asks him if he's looking for a male or female horse.
"A female horth."
He shows him a prized filly.
"Nith lookin horth. Can I thee her eyeth"?
The rancher picks up the midget and he gives the horse's eyes the once over.
"Nith eyeth, can I thee her earzth"?
He picks the little fella up again, and shows him the horse's ears.
"Nith earzth, can I see her mouf"?
The rancher is gettin' pretty ticked off by this point, but he picks him up again and shows him the horse's mouth.
"Nice mouf, can I see her twat"?
Totally mad as fire at this point, the rancher grabs him under his arms and rams the midget's head as far as he can up the horse's twat, pulls him out and slams him on the ground.
The midget gets up, sputtering and coughing.
"Perhapth I should rephrase that; Can I thee her wun awound a widdlebit"?
