I knew there was a reason I was glad to have altec back in the forum. I initially thought it was his extensive knowledge, but maybe it was simply a fondless for his style of sarcasm.

Anyway, since the thread is well and truly 'jacked...
...I wonder if dad still carries that old silver bullet he cast back in the 80's? He cast a number of them (.45's, I think) for some buddies in his RC flying club due to some weird discussion they all had one day. They didn't actually load any of them, as far as I know, and for a number of years he kept it in his pocket with his keys - sort of a good luck charm. I think it's been sitting in an old mug on his dresser for a number of years now, though.

As for the question itself, I'm fairly sure the only way to kill a troll is a profound, cleansing flame. Of course, the collateral damage from said flame tends to be quite high - often killing the troll hunter as well and leaving many bystanders with headaches. Depending on the troll, an alternative is that most devastating of tools: the ignore list, or the conscious act of ignoring.
