Horse-riding is dangerous. Deadly even. Especially when uppity commoners are involved! Mark Phillips is the coach of the US Olympic equestrian team. He has so far killed three team hopefuls this season with his "challenging" new jumping courses. This very much upsets his ex-wife, Princess Anne. "Phillips is about to be crucified as the halfwit menace," said one British journalist (according to Page Six). The problem is that Phillips isn't royalty, even though he was married to a Princess for a while, and only royalty can properly manage this exciting and deadly sport. We don't know if this is good or bad for Lou Dobbs' daughter Hillary, who is sort of American Royalty, isn't she? Thankfully, the world is still eradicating the horse menace. After the jump, terrifying footage of just how dangerous horse-riding can be.
