Okay, I had to try this one after seeing it on Scott's blog. It won't let me paste the results, but I do like them!
Which Sci-Fi Character Are You?
I am Yoda! Yes! Yes!
A venerated sage with vast power and knowledge, you gently guide forces around you while serving as a champion of the light.
Judge me by my size, do you? And well you should not - for my ally is the Force. And a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us, and binds us. Luminescent beings are we, not this crude matter! You must feel the Force around you, everywhere.
Oh, and I love the website's name: tk421.net. I think he/she might be just a tad obsessed with Star Wars, don't you?
Cheers...er...May the Force be with you!
