Why do people stand on horses?

Oh yeah sorry about that. Im new and didnt realize that it would send it to the top of a forum. Sorry...

Ok I have actually see some use this feature with a horse. And the man that did it is a well known trainer. He had my gelding ready for me to pick up and 1 of the requirements was that we would go on a trail ride. They had 300 acres of woods along the Mississippi. Someone had gone into his wood and had put no hunting sign up on his property. He wasn't sure how they got them up that high but as part of our route and not on a trail every so often he would take the horse he was training and sidle him up to a tree, stand up in the saddle and pull the signs down.
Now as far as in the sale barn if I see a person do the stand up on his back, the main thing it would tell me is that they have spent time with this animal and this horse has been handled. Would I do it probably not, but you got to admit that it isn't something you can do on just any horse. And if you are buying a horse for a kid odds are they will try it. I know I did.

I do stand on my horse... However, I do it as a trick rider and always with a proper saddle. Some of these comments are offending but I'm a big girl and can deal with it. I believe it shows a lot of control when standing on a horse. You know that horse knows its job and isn't a spook... Videos probably show this best with standing up. I do like a horse that will do it whether or not they are a trick horse. Yes, they CAN see you on their back, and if their eyes aren't far enough to the sides and they can't see you, they can still feel you. A horse can feel everything you do on their back, every time you get nervous, every time your hand moves a couple inches, every time you scratch an itch they are aware of it, and every time you lean or lay over to avoid hitting a tree, etc. Some of you have a point and others are being plain ignorant!

Because I can ahahahahah. Plus its just fun!!!

The horse is facing away first of all... Second of all, I see the horse listening or waiting for what he/she is to do next.
