A jockey is in the parade ring discussing race tactics with the horse's trainer. The trainer tells the jockey that this is the worst horse he has ever seen. It has had 23 races and finished last in every one of them. If it doesn't win today the milkman will be using it for deliveries in the morning.
The jockey mounts up and takes the horse down to the start.
The race begins and the horse is immediately 10 lengths behind the pack. So the jockey gives the horse a sharp thwap on the shoulder.
Nothing.
