Few moments ago saw an interview with a passenger who was sitting in an exit row (so he claimed). When he realised they were headed down said he scrambled to find the briefing card on how to open the exit as he had not a clue. So much for listening to the brief and understanding your responsibilities sitting in that particular window seat. Different circumstances (smoke filled cabin on the runway) may have seen far different result if relying on this individual. Interviewer never picked up on the point.
