Perhaps getting a bit off topic, but when playing rock-paper-scissors, for multiple rounds against the same person consecutively, I've noticed that people tend to throw what would've beaten the last thing you played, so you just throw what it takes to beat that. I used to tell people I'd be able to beat them pretty consistently at rock, paper, scissors..of course, they think it's random and that I can't consistently win. If they take me up on it, we play 10 or 15 consecutive rounds, I beat them over and over, and then explain what I've observed/how it works.
