Fellow approached a neighboring farmer and said he needed to buy a horse, nothing special, just a plodder to ride to town occassionally. "How 'bout that old nag there in the pasture?"

"Well, I don't know, he's in kinda bad shape, looks pretty poor."

"It's OK," says the neighbor. "He'll do."

So the transaction is completed and off he rides, only to return an hour later bruised and soaking wet.

"You didn't tell me he was blind. He stepped off the bridge and dumped me in the creek!"

"I told you," said the farmer, "he doesn't look so good!"
