Take your lead from movements you respect
Pretty much every Yes Men project has taken its lead from a movement or campaign we respected. It just makes sense.
At the very start, in 1999, the (looming) Seattle protests inspired us to set up our very first fake website to mock the emblem of global capitalism, the WTO... which led to torrents of email meant for the WTO and, eventually, every other project we've done!
In 2002 and then 2004, too, we followed the lead of a campaigner at Greenpeace... and found ourselves in a surreal TV appearance that's still our most effective action to date.
We also took cues from Occupy Wall Street: consciously at first, egged on by a revolutionary who'd helped bring down a dictator, and then because every progressive in America was taking cues from that movement or the campaigns that followed. We can now say that most of the actions we've been involved in since 2011 have been in some way related to OWS.
