Yes, it's seemingly a nonsensical rhetorical question, but, for that precise reason, it will illustrate a lesson, if you so desire to tag along for this short session.
Per Wikipedia, "The horse (Equus ferus caballus) is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae." Hmmm... I much prefer that the horse goes "Nay," eats hay, has a mane, and is ridden by cowboys, cowgirls, Indians, equestrians, knights, jockeys, conquistadors, Mongols, and all. Even better, just point a horse out or otherwise show a picture to a kid and they will never be mistaken again. Even the littlest ones will never be stumped when faced with a rhino, tiger, giraffe, camel, and such.
Admittedly, there is a worry that we could be fooled with that of a donkey or mule. How come no one has taken advantage of this?! What a scam to get us rich! "Duh doy," you say, cause we all know when we see a horse, so why would anyone try to trick us with an ass?! Well I ask you in turn, why does anyone try to trick us with good art versus bad let alone art versus crap? How could anyone fall for that?!
