Paul O'Neill took a page from Zidane and head-butted his horse. Zidane was at least provoked. O'Neill just lost his head and got frustrated with his unruly horse and took it out on him. Hope he gets fined enough to support the horse for the rest of its life. The oddest thing is that the jockey probably precipitated his horse's unruliness by being tense and angry. Animals react to the mood of their person, just like our doggies who disappear under the couch when they sense that we are angry.
