Found few personality tests and quizzes but didn't test them because I'm in school and I'm a closet brony.
Edit: I came up with a question which is a bit related to ^: Have you tried to get anyone to watch MLP with you and if you have, how did they react?
I watched the first the episode with my little sister (who is 19) and with our family gay friend (23). First they laughed at me and when we started watching, family friend said "I wouldn't have believed that you would watch shows like these". And when we finished, my little sister said that "it's not my thing" and family friend said "Nah". I wasn't able to get them watch more episodes.
