I fill them with nonsense words unrelated to the question. Mother's maiden name? Fire truck. First car? Air conditioner. If I have to call a company they always ask me why. The explanation is anyone who has me as a Facebook friend can figure out who my first girlfriend was, my maternal grandmother's first name, my mother's maiden name, where I was born, my first car, etc. And if every company has the same data, a data breach at one makes the entire system fall apart.
