Kanye owning a horse makes a lot of sense, especially if it's a weird horse like that. He's weird like Michael Jackson in that way. Not many superstars could pull off having a zoo and theme park on their property, but Kanye is up there along with Elton John. There's no reason to not own horses when you're that rich. It just feels good to say "that's my horse." Try it while pointing off into the distance. It'll make you want to get a horse. Go check if it's cool with your landlord.
One day we'd have to go through seeing a tweet that says, "my horse died." 10k likes. 26k retweets. Then Kanye could focus on better things like getting a unicorn. "We got the best experts at Donda looking into unicorns right now."
