We have a game that probably 99% of the people in Israel play. It's actually a game you're not supposed to remember, meaning you simply aren't allowed to remember it, and if you do remember it, you can mention it to others. If you haven't remembered it for 7+ years, you’ve won and you can stop playing. Now, because I told you about the game, you’re playing it too. It's weird, but if you ask any Israeli about this game or just say 'Shit, I remembered,' they'll know what you're talking about.
