The film The Yes Men Fix the World gives us a front row seat at several of these jaw-dropping, hilarious stunts, and takes us behind the scenes to show how they are planned. In this movie, there were several times that I could not find what the two men did funny because it was a bit too much. But as a result, it was an unique and effective way to make people realize that the situation now they are ignoring unconsciously is weird and needed to be solved.
For the fake New York Times, when people got them, they quickly knew that the news were fake ones but they were laughing and most of them did not get angry about it. Of course I cannot always agree with the idea of telling lies trough media but since we are relying on media too much, it sometimes could lead an interesting result.
