Sorry guys. This is a horse who is patient, extremely forgiving of mistakes, and who, if you ask him to, will pack around a sack of rocks or a couple of goats without blinking. Fortunately for your manhood, these horses are an urban legend, an fall into the same category as the Bomb Proof horse and the Babysitter.
Sale-ad wise, it’s three ways of saying the same thing: this horse if far too old and creaky to do anything but walk slowly for brief periods of time. A realistic translation of a younger horse that is labeled Husband, Bomb Proof, or Babysitter would be: pretty quiet, mostly reliable dude. Except when he’s not.
