I remember reading a mystery by Isaac Asimov where the brilliant detective determined the identify if a spy by quizzing him on the national anthem. The fact the he knew there was a second verse to it and knew the words proved he was a spy because no actual American knows this.

When I was in highschool a college friend obtained for me a fake ID, which I had to memorize so I could go drinking with them around campus. By the time we got to the fourth bar, my cognitive abilities were fully lubricated (not in a good way) and the bouncer asked me what my middle name was. I quickly blurted “S”
He said he was going to have to keep the ID and that was not admitted. D’oh!
