I just took the Dr Who Personality Quiz: Which Doctor Are You? http://www.bbcamerica.com/anglophenia/2013/11/personality-quiz-doctor/
And it said;
Your result: Congratulations! You're the Eighth Doctor
You're a true romantic, a real believer in the power of people and their collective abilities.
You may have seen some unpleasant things in your time, had to deal with traumatic events, but you've never let them soil the purity of your faith in the basic goodness of humans, and this is written across your face.
It's a hugely attractive feature, and this can sometimes lead you into trouble. but people generally feel better for having spent some time in your presence.
This is the Dr I know the least about (since he had one movie), I herd he has some radio stories or books that fill out his time as the Dr but I don't know anything about them. Interesting!
