As for me
I was sitting on my stallion facing the wrong way ( yes ! Looking at his rear ) , My horse had - No saddle , bridle , rope , headcoller - actually he was wearing nothing at all and I accidently touched his hind quaters with my foot . I caught him by suprise and he bucked twice and I landed on my face in the sand.
After I had dragged my carcass off the floor I got straight back on him ( aren't we supposed to learn from our mistakes )
Nutty by name and I suppose nutty by nature !
