西 = 兀 + 囗 : Marie Curie has gone crazy from the loneliness in space. In front of the space station, she sits inside of a large wooden box, wearing a cowboy hat and playing a 胡兀尔 fiddle, thinking that she's participating in a square dance in the wild west.

周 = ⺆ + 土 + 口 : Mnemonic symbol: a hula hoop. James II of England (zh) performs in front of the outhouse (ou1): he swings a hula hoop (周), juggles three mandarins (口) and balances a small heap of dirt (土) on his head. He cheated a little bit though, because he stapled the heap of dirt to his wig with a stapler (⺆).
