How well-trained are your horses?

I'm just glad Jennifer is a horse, a real horse. And that's cool, I had a donkey named Doc that was 14 hands... he knew how to kick the dog, make that crazy noise at first light, and hide in spaces much too small for a large donkey, making him a very good prankster.
Any chess horses, or do you glue factory them ASAP as many people do?
