Funny story Sherm, unfortunately I actually did that. I worked at Dairy Queen when I was 16 and they still used these. I was washing the window where customers walked up and ordered from outside and the reciept spike was sitting on the ledge. When I was wiping downward it ran right through the meaty part of my forearm just missing the bone and going all the way through. It was really gross but amazingly it really didn't hurt. I covered it with the towel I had in my hand and went up to the owner and told her I had a little problem. She gave me a sharp, annoyed response that she was busy right now. So I moved the towel and stuck my arm in front of her face and told her it was kind of important. I will never forget the look of horror on her face.
