When I was in preschool (3 or 4), we used to have a gym that we used an old dark staircase to get to. The teachers didn't want us to fall so they sang a song about keeping your hand on the railing. It went to the tune of "if you're happy and you know it" except the words were "keep your hand on the railing on the wall". My child brain thought that they were telling you to put your hand on the railing and then put it on the wall. So I was constantly switching between railing and wall. I only recently realized that they meant that the railing was on the wall.
