I remember when...

First, this goes into the "some people have too much free time" category-- it's a timeline of world events as presented in the movies. Starting with:

A long time ago... Luke Skywalker and Han Solo lead a rebellion against the evil empire(Star Wars) 26,000,000,000BC Los Angeles (and everywhere else) - The Earth's crust begins to harden (Adaptation)

and going to:

30,000,000 Earth frozen by an eclipse, intelligent life wiped out, day and night now the same (The Time Machine) 865,427,810 Alexander Hartdegen briefly arrives from 802,701 (The Time Machine)

Second, a subversive campaign that places empty speech balloon stickers on ads in the public environment -- which practically beg people to fill them in with whatever they feel is appropriate. For instance, a speech bubble on a male model holding a laptop in an IBM ad says, "I use it to download porn!" Ha! I saw these when I was living in NYC.
