This is a skit we do at camp so I'll do my best to turn it into joke form
A man goes to buy a horse, the owner who speaks very poor English tells him "he not look so good"
"what are you talking about? He a beautiful horse!" the man argues
"he not look so good" the owner insists
The man, now irritated tells the owner "he's a fine horse and Id lime to buy him."
The owner tries again to dissuade them man "he not look so good"
"look!" says the man "is he for sale or not!?" and the owner relectant sells the horse to the man. The man gets on and the horse runs him I to a wall. Angry he goes back to the man who sold him the horse "hey! Yu sold me a BLIND horse!" to which the seller replies "I told, he not look so good"
