Guy calls his buddy the horse rancher and says he's sending a friend over  to look at a horse. "How will I recognize him?" he asks."That's easy, he's a midget with a speech impediment". So, the midget shows up, and the guy asks him if he's looking for a  male or female horse.  "A female horth." So he shows him a prized filly.

 "Nith lookin horth. Can I thee her eyeth"? 

So the guy picks up the midget and he gives the horse's  eyes the once over. "Nith eyeth, can I thee her earzth"?  So 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 pissed 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 pissed at this point, the rancher grabs him under his arm and jams 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 widdle bit"?
