A man is driving down a country lane and sees a sign that says ‘racehorse for sale, £20’ He thinks 'what a bargain, I’ll buy it’s, so he goes to the farm, gives the owner a £20 note and asks to meet his new purchase.
The farmer lets the horse out of the stable and it rubs fast as lightning, straight into a wall. The man thinks it’s a bit strange but you know, these things happen. The horse then sets off again, even quicker, straight into a tree. The man is a bit suspicious now but gives the horse one more chance.
The horse gets up and is off, faster than any horse has ever run, straight over the stream and into the woods, never to be seen again. The man is furious, ‘You’ve sold me a blind horse’ he shouts. Very calmly the farmer replies ‘oh he’s not blind, he just doesn’t give a fuck’
