Who's greatest contribution to mankind was three thousand posts of simplistic egocentria; a collaberation of half-baked concepts and ideas, pseudo intellectualism fused with an uncanny, pathological system of towering repitition, which no one knows of beyond this minute speck of cyberspace we call Troll Kingdom. Not even in this small community do you have any genuine recognition; already you have destroyed your own carefully constructed gimmick through your own increativity, in which you have by your own hand been reduced to nothing more than a parrot who repeats the same tired slogans. If you are ever remembered, no stories will exist of your self inflated pretend past. You shall be remembered as nothing more than boring impotent, which you have reduced yourself by your hand.
Mankind's greatest contribution? You havn't even built a Pyramid, n00b.
