I rode a horse I absolutely never should have gotten on, but in my defense it was for 2 minutes and it was in an attempt to help save him from going for meat. He was supposed to be a Shetland X Mini, but I swear he was just a really stocky Mini. He kept bucking and misbehaving for the girl riding him, and she was getting scared and compounding the problem. She was supposed to be training him for sale, so anyway I got on, he pulled a few tricks, I got him to canter nicely and then after that he behaved for her.
I'm pretty sure he ended up going for meat ANYWAY, so I won't ever put my moral compass out again by getting on a horse that small.
I sat on our mini Alice for a split second. When I was a teen I knew someone who did pony parties. She had a couple of Shetlands, one was about 11hh and we used to ride him around the barn to do stuff because he was so laid back. Mind you I was a good 70 pounds lighter back then.
12 hh pony thing. No idea what breed, probably haflinger x shetland. He liked to do these little half buck things, we used to joke that someone stuck a quarter in him. After he realized that the rider wouldn't put up with his shenanigans he would behave. I ran 19 second barrels on him for fun, lol. For an obese little pony he did pretty good.
