For threads... What was the Microsoft Paint series someone did? That was one of the funniest I've ever seen.

I went through a while back and tagged some of the more memorable threads here with the "classic moments" tag. That's a good place to start. There's a couple that look like they were auto-tagged and aren't really epic threads (the first 2), but it should be a pretty good list. We should probably get a mod to change the tag to something more unique, so that it won't be auto grabbed by threads that aren't relevant. http://bbs.clutchfans.net/tags.php?tag=classic+moments
