So the moral of the story is not to let people play stupid tricks on your body without demonstrating it on themselves first; I mention this because a friend of mine was very badly burned on the back of the hand once; someone in a pub offered him a £20 note, the condition attached was that he would have to hold the note against the back of his hand and let the trickster burn through it with a cigarette.
Trouble is that the skin absorbs the heat straight through the paper, which consequently never gets hot enough to burn through.
