I really couldn't believe the Doctor's Daughter on that count (though I thought the episode was fun overall).

I mean the whole "Look up genocide in the dictionary and you'll see my picture there because I've already been there, done that and even erased them from all of time, bitches" to Jesus Doctor's "I never could (I just make other people do it for me) so base your society on my moral teachings!" I wish they'd go back to a time where every episode wasn't a morality play.
