Loosely inspired by this youtube video, I give you Stump the Fanatic.
Rules of the Game:
There is one and only one 'fanatic' at a time. The goal is to ask a question of the fanatic in his or her chosen subject-field which the fanatic cannot answer, or to which (s)he gives a wrong answer (i.e. to "stump" the fanatic). The poster who does so becomes the next fanatic.
The fanatic sets the parameters for potential questions when he or she first becomes the fanatic. A fanatic can choose anything within the world of entertainment -- TV shows, movies, books, plays, poetry, music, sports...basically anything that has an audience of some sort (but don't pick something too esoteric or no one else will be able to play, and that won't be very fun).
The fanatic on the hot seat is honor-bound to only use his or her memory of the subject, and to not use the internet or other sources to answer the questions. After all, if you have to use Google then you really can't claim to be a true fanatic, can you?
Questioners -- don't ask questions which you cannot answer (though you can use Google or whatever as much as you want), or which have no definite, single correct answer. In other words, don't ask what was in the author's mind when he wrote X, or ask questions that require subjective evaluations. Just factual question, please. Also, please only ask one question per post (or one question with several parts).
Acceptable answers: since this is all from memory (assuming you are honorable), exact spelling and exact quotations are not required. So if the fanatic remembers "D'hoffryn" as 'Dahoffrin' or anything that is recognizable as the correct answer, then that answer is acceptable. If the fanatic gives an answer that you believe is wrong, provide proof that it is wrong (i.e. links, citations, etc).
I'll start. My chosen field in which I claim expertise is the so-called 'Whedonverse' -- i.e. the TV shows Buffy the Vampire Slayer and Angel. This does not include the comic books, the movie, any novelizations, or anything else that was not actually on screen as part of those two shows. As an added restriction, I don't pay close attention to credits, so don't ask any questions about who wrote or directed given episodes, or who the assistant to the set manager was in episode 3 of season 1, or whatever. In other words, just ask questions about details of the story and characters, please.
As an incentive, I will be giving rep to whoever can stump me (and I invite everyone who participates to do so as well)...
