This might be fun. A local radio station is putting together a questionnaire that would hypothetically be used to pinpoint somebody's identity. They're looking for questions, not the answers, that would be asked to get to the true person.
Some of the entries are: If you were a crossword puzzle clue, what would you be? What piece of music would you want played at your funeral? If you could spend 10 minutes with any person, living or not, who would you choose?
My identifier would be: Recite one passage of any Shakespearean play and answer why that passage is memorable.
Any others anyone?
