 wiring one up that sat kind of next to me um but was far enough away that it didn't bother me but i had a an electric baby grand at the time which is a very big keyboard and he was underneath it doing it and the guy out front didn't realize it and he hit the switch and it blew up and he raised his head up and hit the bottom of my keyboard and knocked himself right out of course we didn't help him he just looked there and laughed at him
