I only ever do the ones that are blatantly frivolous, like "Which character in a major recent media property are you?" (someone called Littlefinger from "Game of Thrones" which I don't recall if I bothered to look up, since I have never watched the TV series, and hurled the first book aside in irritation at how dull it was...it was at least a nice, memorable name, which is why I remember it).

Personality-related questionnaires, whether serious or frivolous, always fall down by failing to make the distinction between personality traits and actual behaviour. They are also seem to be always designed for and by Americans.
