this wasnt in the house but the back garden, a friend and I had a target set up at about 25yds with a net behind it, to stop stray arrows going in the neigbhours garden. I asked my friend if he could shoot left handed, so he tried, the arrow went over the net, through the window of the negibhours shed, leaving a clean arrow sized hole and stuck in a piece of wood the other side of the shed. It was pretty embarassing to explain things to the neigbhour, but he was very understanding!
