One night at my church youth group, I thought I played the best game of Mario Kart in my life. Somehow the controller perfectly interpreted my moves better than it usually did - I wasn't crashing or going the wrong way at all! At the end, I realised I had actually been watching my opponent's screen, and I'd never caught on that I wasn't actually controlling it. Meanwhile my character had just been careening randomly into the side of the racetrack.
