First video - nothing funny at all, a bad fall pulling on the bridle, horse almost went full blast into the wall and his tongue was stuck over the bit - not nice...
Second video - something, not the plastic, spooked the horse to hell, suprised the rider stayed on, but she kept pulling on his mouth as well.. I guess I am not able to look past that anymore, and I guess the horse has a few bruises now from hitting those walls.. he was scared blind barely able to avoid anything in his way!
Third video is a load of fun, shetland races??? O_O they should do some more.. reminds me of the pony "circus" we did a few times a week - let all the ponies run together in the manege, they had a load of fun apart from the mini shetty, he tried to stay in a corner all the time :P
Fourth - Ed is a funny pony
but I think he is a bit dangerous for the kid too! And its almost a learnt response - every time the kid uses the stick, the pony part rears and kicks out! Soon to learn a capriole?
And LoveDressage's naked jumping video O_O holy mother.. but ye, its fun
