The lad cannot believe his eyes as he watches chief slowly drilling a hole through his blackened thumb nail.
"Blimey Chief what are you doing?"
"Well son , what has happened here is that I have twatted my thumb nail with a 4 pound maul which has caused it to bleed under the nail . The pressure of the blood has caused some discomfort and so I am using this small jobber drill to put a hole in the nail to relieve the pressure"
"Doesn't it hurt?"
"Only when I centre punched it!"
