It reminds me of a joke I heard:
I man is walking down the road with a horse on a lead ... it's a very handsome black stallion and attracts a lot of attention from all who see it.
He is approached by another man who comments on the beauty of the animal and says he will buy it at whatever price the owner asks ... the man mutters "He no look good!" and walks away. Not to be shaken off easily the wealthy potential buyer follows him and keeps offering higher and higher amounts to which the owner responds in exactly the same way ... "He no look good!"
Eventually the owner is worn down buy the ever increasing offers and the money subsequently changes hands ... the horse is passed to it's new owner who proudly leads it home to brag of his new possession to his friends.
The next day he discovers that the horse is actually completely blind and is so incensed that he was duped that he contacts the seller and demands his money back ... but to no avail.
The seller's response was simple ... "I told you but you didn't listen, that horse, he no look good!"
