When I was in elementary school, there was an assembly. After one of the performances, one of the teachers yelled, "lets give these people a round of applause!" and she started clapping while moving her hands around in a circle, so I naturally believed that that was what a "round of applause" was. For years after that, whenever people mentioned a "round of applause", I would start clapping my hands in circles, wondering why no one else was doing it properly.
