I wanted to have my tounge pierced, abd a friend told me a cheap way to do it....?

so we went to a mutual friends house, and they told me to stick my tounge out and close my eyes! Well, all of a sudden I hear BOOM and I feel this horrible pain in my tounge and jaw. Well, thewy used a nailgun to pierce my tounge, but had the gun on a bad angle. Now My tounge is pierced, but its nailed to my chin too! I dont want my parents to find out, and i dont want to go to the hospital because they will call my parents! We think the nail is embedded into my chin as I let them try to get it out with a hammer claw, and it hurts too much to do it that way. Should we just use a hacksaw and cut the nail under my tounge and just hammer the nail into my chin to hide it?? Think this would work, and just put a bandaid on it to hide the hole??? Any suggestions....HELP!!! Its hurts!!!!!!!!
