The Internet's most detailed which-superhero-are-you quiz. In my case I was pretty sure where I was going to wind up after the first few questions:

Are you an intelligent geek? Do you like redheads? Are you accident prone? Do you have a good sense of humor? Do you like hi-tech gadgets?

Sure enough, I came up with a nearly 85% match for Spiderman. Second place was a dead heat between Green Lantern and Superman. I'm sure I would have scored higher as Superman if not for the "Do you like to fly?" question. Of course I hate to fly in an airplane. That doesn't mean I wouldn't want to fly under my own power...
