He can blow despite having a horse throat.
When J.D. the horse recently turned four years old, his trainers at Ithilien Stables in Whitehouse, New Jersey decided to surprise him with a birthday cake, complete with flaming candles. J.D., in turn, decided to surprise them by blowing out the candles all on his own.
You've got to admit, that's a pretty cool trick for a horse. It almost makes him seem human. Almost. If he really wanted to seem human on his birthday, he should get very morose for no good reason and then go sit in the corner and think about how what a failure he is. And then he should get drunk. You know, like all of us do, right?
