It explains how to be funny and not just stupid.
Whoever claims that this pile of shit called "encyclopedia dramatica" is better than uncyclopedia, is either someone who goes there to get free porn, or a retard who prefers laughing at a four letter words and incoherent sentences, instead of a clever thought-out article that is actually funny. Also, these folks from encylopedia dramatica tend to criticize uncyclopedia's admins for deleting every article users create, but everybody knows it's only their articles that always get deleted, for being way to stupid and generally shitty.
PS: Some other writer of urban dictionary said uncyclopedia is written by kids, but let me tell you that if there is one site that's written solely by kids unable to speak english, this would be encyclopedia dramatica, with it's lousy pics (can't these kids retouch something properly?), pathetic homepage, and ful of in-jokes like "the lulz".
