True story as told to be by a blacksmith and racetrack character.
Once upon a time there was a mare who seemed nervous and like an underachiever based on her talent displayed at times so the owner told the trainer to put a goat in with the mare.
The trainer did so and the mare continued to run poorly. About a year and a half later, the goat got sick and died.
Shortly after that the mare displayed a complete form reversal and won 4 races in a row including a stakes race. The owner asked the trainer what he thought caused the turnaround and the trainer replied " I'll tell you what happened, that goat was driving that mare ****ing crazy!!!!!!!" LOL!!!!
