in this game, two players make an arch while the others pass through in single file while singing a song. the arch is then lowered at the end of the song to "catch" a player. perhaps the most common example of such a game involves the song "london bridge is falling down." a similar game is played to the tune of "oranges and lemons." similar games exist in other cultures as well. in japan, for example, similar games are played to the song "toryanse." in mexico, the game is played to the song "la vibora de la mar."
