Hmmm, if I answer seriously I'd probably let at least one person down, possibly more. I could say Sidorio, since his spam is bitter and unpleasant while remaining somewhat serious, but only users who have been around a while will understand me and rage appropriately. On the other hand, if I go for an all-around contemporary bad response, the best I could give is this guy, and he's not even on NG.
There's just no fully satisfying answer. Take one of those links and PM me which bothers you the most.
