Your favorite childhood game.

This is a game I still play today: whenever I walked on the tiled floors at school or on the street, I'd try to step on every other tile when I took a step. So for an example: Step->skip over this tile->Step->Skip over next tile-> Step. I was amazed to hear that someone else thought up something like this: apparently, this game is described in the Hanako ending of Katawa Shoujo.

I still play that when I go down to the kitchen or something. It's actually a pretty popular game, apparently. It's like a different version of "The floor is lava".
