One day a man passed by a farm and saw a beautiful horse. Hoping to buy the animal, he said to the farmer: "I think your horse looks pretty good, so I'll give you $500 for him."
"He doesn't look so good, and he's not for sale," the farmer said.
The man insisted, "I think he looks just fine and I'll up the price to $1,000."
"He doesn't look so good," the farmer said, "but if you want him that much, he's yours."
The next day the man came back raging mad. He went up to the farmer and screamed, "You sold me a blind horse. You cheated me!"
The farmer calmly replied, "I told you he didn't look so good, didn't I?"
