Wow, I hadn't seen this before. Dane Carlson has a page listing many many many (1485 to be exact) Which * are you? quizzes. Some of the links don't go to quizzes anymore, but it's still an impressive list. It includes such classics as:
- Which Squirrel Are You
- Which smilie are you?
- Which Sailor Senshi Are You?
- Which Marc Almond are you?
I love it.
