Horseshoes and Horses glitch

To get on the horseshoe:
1: Be at the horse's only party
2:Stand on either the inside or outside of the trough.
3: If you are on the outside of the trough, click and hold the inside of it. If you are on the inside, the other way around.
4: As you you start going to the other side, still holding down the mouse, bring it onto the trough.
Voila!~
