I know far too much about three things. Try to stump me.

Quiz me on . Ten questions, one at a time, starting easy and ending at a level only a real fan would get. Mix the three topics. If you don’t know one of them well enough to write fair questions, say so before we start and I’ll swap it. Wait for my answer, tell me if I’m right, add one sentence I probably didn’t know, and keep a running score. Only ask questions whose answer you’re sure of, and skip anything that may have changed recently. If I challenge an answer, don’t give in to be polite and don’t dig in to save face: tell me how confident you are and how I could check. At the end, give me my score and the topic where my knowledge runs out.
