I think sometimes we are in "awe" of stupid people.
Titan, you're right. It looks like something is going through his muzzle.
The bottom line is, there is stupidity going on in the horseworld. Whether it is speed racking on pavement or doing a piaffe on cement, tied to crossties to music for almost two minutes. Who knows how long he was going before the music/video started. Amazingly, the horses just do it and put up with the stupidity.
