Ah, well, this wasn't me, but it did happen to my friend, he went for an interview at UCL for Medicine, and he thought the interviewer asked him, "What do you think of the BNP?" and he thought, Odd question, but just roll with it, so answered, "Well, I think its up to individuals if they want to be part of an extreme party."
However, a few moments of bemused expressions on the interviewer's face later, and a quick explanation by said interviewer, revealed that the interviewer had actually asked this; "What do you think of Baby P?"
