This was maybe 25 years ago now. Myself and another player in our current group used to play in a campaign where some of the players... tended to do a lot of stupid and dangerous things. Not even always intentionally. The players were just that dense sometimes. They were great guys, they were just the type to investigate a strange panel in the dungeon floor by standing on it. Or starting a fight with a heavily telegraphed dragon masquerading as a human wizard... who we were sent to ask for help.
It became a bit of a trope that these PCs would always start out every encounter, room exploration, etc. by going right and then doing something stupid. At one point me and the other player just looked at each other and we said, "We step to the left." Going left became the way to say to each other that we weren't doing something stupid. And it kept our characters alive and saved the party more than once.
So whenever the DM asks, "Which way are you going?" the answer is almost always, "We go left."
