A travelling salesman stopped alongside a field on a country road to rest a few minutes. The man had just closed his eyes when a horse came to the fence and began to boast about his past. ""Yes sir, I'm a fine horse. I've run in 25 races and won over $5 million. I keep my trophies in the barn."" The salesman worked out the value of having a talking horse, found the horse's owner and offered a handsome sum for the animal. ""Oh, you don't want that horse,"" said the farmer. ""Yes I do,"" said the salesman, ""and I'll give you $10,000 for the horse."" Recognizing a good deal, the farmer said without hesitation, ""He's yours."" While he wrote out his cheque, the salesman asked, ""By the way, why wouldn't I want your horse?"" ""Because,"" said the farmer, ""he's a liar - he hasn't won a race in his life.""
