Best Trolls?
Hmm...
It's hard to judge. I can surely list a lot of failures. Wait, no I can't. I don't remember any of them.
The ones I do remember are the funny ones. Gagh is surely among my top three. I saw him controlling posts at STCCGBBS many years ago. He was a high caliber troll even then. Though, he just didn't know it.
After that, I'd say Joker. He was the first person I remember trolling this board. He came through with his dual Bane. He even got himself truly hated by members of LoNAF and STBBS. Unfortunately he's found himself a life selling comic books (go figure, a nerd who leaves one nerdy arena to deal in another).
Lastly, Missmanners. Because we are all her duals.
