I have a full black fingernail from an injury at work. After doing it, suddenly I turned into a born again Christian "Ah for the love of Christ" I screamed. "God this f*****g hurts...". Three weeks ago and it's still black as night and people think i've painted it that way - not good. In situations like this my grandad used to rip the nail off with a nail (sometimes he put electric drills in his mouth to rid of teeth). He's dead now. For one of the most smartest people i've ever known he was a little mental.
