I have had interviewers ask me these questions.

I have also asked these types of questions. I ask it to try and get the candidate to divulge a little bit of character.

When I am asked these types of questions, I don't bother with trying to decipher the undertone. I just answer with my personality. If they don't like the answer - then fine. I won't sweat them not liking my answers to the oddball questions. In the end it probably means I wouldn't be a good fit.
