Ancient.
There needs to be a website called "StartHereForumNoob.com" or something like that that has EVERY old / ancient forum thread. This can include:
-- The 3d chalk sidewalk drawings
-- A rant thread about the nigerian scammers
-- The video of the F14 toy airplane set to the Top Gun theme
-- The Mentos & Diet Coke guys
-- The definitive "chuck norris" list
I'm sure y'all can come up with this list better than I can. But every forum, at every time, has these threads. Someone make a place to send people.
