Here's a story I like to tell about how smart goats are...
I had put in a new barn for my does and I never thought to put the light switch out of their reach. One night, we could see that the light in the barn was on, I knew I had turned it off when I left, so I yelled out through a window; "You girls turn off that light!" The light went off. Whenever I saw the light on, I could open a window and yell at them to turn it off, and they did. Off course, eventually I moved the light switch out of their reach.
