I've spent a hell of alot of time around animals, and I can tell you the last time I saw a heifer in heat, considerably smaller then this horse, try to mount a 4H kid I was scared for the little guy's health. I appreciate the strength required to hold the front half of a horse up, however:
It looks suspiciously like the horse is trying to make a man out of that Finnish gentleman.
It's still wierd.
Those are the only humble observations I wished to make.
