I don't thin that faking a death in a tragic and dramatic fashion is a good idea. The police investigates deaths that are in tragic and dramtic fashion.
There are probably much better publicity stunts. The most straightforward that comes to my mind would be having sex in the MoMA. You'll need a person to fill film it for youtube.
Afterwards I think all the art folk will talk about the issue.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
