DRM is funny [Comic]

This comic from the excellent XKCD site pretty much shows you why DRM is such a great idea...if you don't want people reading your work. Think about it, do we really want to erect barriers for potential readers? Could they, perhaps, go read someone else's work instead? http://xkcd.com/956/

(For what it's worth, I don't like 'The Giving Tree' at all).
