I think I have the greates funniest quirk ever, my horse I swear has ADD so bad.
I ride him in a Tom Thumb Pelham, and trust me it's bc he likes it, I know that sounds weird but he does. Well whenever we're standing too long, he starts shaking his head up and down to play with the chain! I mean how weird is that, lol.
I remember once we were at a show and all the horses were lined up in the middle to receive our ribbons and everybody else was standing quietly and of course, it took too long and my horse gets bored and starts shaking his head up and down to plain with his curb chain, omg was I embarassed! Lol he doesnt do it at shows ne more, when he did it that one time he was only 4 but he still doesnt at home to keep himself occupied, I have a weird horse!
