(Re Godwin's Law: Is it still mentioning Nazis in vain when it's about someone calling for mass sterilisation of "subhuman vermin", as opposed to advocating their text editor preferences or whatever?)
I picked all but two of them correctly. It was the use of language that gave it away though.
I like the clear linguistic differences pointed out by one weblogged: Nazis tend to speak about genocide as a justice issue...a national duty. Footballers speak about it like it's a spectator sport.
I think this is the exception that proves the rule. Or, another way of looking at it: LGF had already self-Godwinned before the quiz was made; all the quiz does is lift the lid.
