The 'Poor Setekh' one loses something in the translation, there were pictures involved. Basically, it's all that was left of a very classic thread indeed.
As for the others, they were from General Discussion, and are general discussion, they don't stray too far off topic throughout, and were first of a kind, like the Torpedoes thread, it's not that they are 'great' in content, but they were 'unique'. The Fake FS3 one is classic because the person who edited the image of the XBox 360 list to include Freespace 3 was Goober5000, and it was caught up by the gaming press as serious. I'd say that is more than a little classic.
I'm not vehemently against the Bumper-sticker one, though I think it would need pruning, but certainly the void of Spam should remain in the pit.
