One for Sorrow

I wouldn't say Sayid's "the bungler" because that, to me, assumes that his failed actions are in some way purposeful. He's more of a "bumbler", I'd say. He comes up with perfectly good ideas (using tarps to catch rain water, triangulating the signal, etc.) but something beyond his control always happens to mess it up. Either it doesn't rain, or he gets bashed on the back of the head with a club, or something. He's a bit of a bad-luck magnet, in that respect.
