I can imagine. Is it possible to teach a horse to back up an piss on people on demand?
LOL!! I don't know about that, but I know that it is possible for a horse to know, whether through Devine Intervention or what ever, to know when it's time to $hit on somebody. I was pulling my 2-horse trailer, with Tennessee in it, across the dam and there was this goober in the car behind me who was really tailgating me. I wasn't about to go faster because the road across the dam is only 2 lanes and they're REAL narrow, so I just ignored it kept on moseying along at my same speed. But I happened to look back again in my side-view mirror and the goober had dropped WAY back and I wondered why, until I saw Tennessee's tail whipping in the breeze behind the trailer and figured it out. Hopefully he dropped his whole load right on their hood! LOL!
