I have created the Rick Roll Timeline, but since the picture I post here will be tiny, I'll just give the outline:
--First rick-roll; people think it's funny
--Rick-rolling goes apeshit; unknown links are rendered virtually unclickable
--Rick-roll gets mention in major newspapers
--Rick-rolling declared "uncool" by Internet community
--Rick-rolling becomes media darling, earning time on VH1s Viral Video Countdown
--Rick-rolling makes comeback in ironic form
--Resurgence of rick-rolling causes mass riots and looting; end of world.
