That is too cute!
YOu know, I read this book a few years back, true story, about this horse that was a sensation at the end of the 19th century or early 20th century for being able to spell and answer all kinds of questions. His owner, a black former slave, had started out teaching him all these things when the colt started to play fetch with him, having seen the dog do it.
The horse was "Beautiful Joe" or "Beautiful Jim" or something like that. Wish I had more memory left in my head. Keeps leaking out.
