I got my cartilage pierced once. And they used one of those hollow spike thingies too, not a gun. I had already gotten a few tattoos and I figured that this would be over in a few seconds so it wouldn't hurt that bad. Holy crap was I wrong. I saw a bright flash of light and next thing I knew there was a small chunk of my ear on the tray. I joined the military a few months later and had to take it out. But man did that surprise me.
