My sister had horses.
One was a Tennessee Walker, which I loved. Wow, was it FAST! People that raced Quarters asked her to run with them to help increase the speed of their Quarters. It was no comparison and never a close race. Named it RingGear because it walked sideways when it was young. They probably didn't expect it to grow into such a high speed runner.
She also had a horse that they ironically named Joker. He definitely grew into that name. He was ALWAYS playing jokes on people. I remember working on my Jeep and it stole my wrench. I had to chase it for 5 minutes to get the wrench back. It laughed the whole time. He would walk towards me slowly and as soon as I reached up toward the wrench, he'd laugh and run away.
He would also poke you on the shoulder then hide on the other side of you. It would stair at the sky and when you looked up, he'd lick your chin. Nothing but laughter, all the time. 4951
