I really hate to be a "me too" poster (sorry, Derek), but I had to preach the gospel of dickipedia.org, hilarious parody of wikipedia.org and skewerer of celebrities.
I found the entry for George Lucas exceptionally good.
I'm so glad there are some razor-sharp humorists out there. The Onion, The Daily Show/Colbert Report, and 23/6 to name but a few. 'Cause the moment we stop laughing at ourselves, folks - it's over.
(The laughing at ourselves link goes to a Lewis Black routine - it contains profanity and is not kid or work-safe).
