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.

乡 = 幺 + 丿 : Mnemonic symbol: a tractor.

乡 = 幺 + 丿 : Marie Curie's tractor got stuck in a pile of bananas in front of the anglepod, with the wheels spinning helplessly. Her last hope is that she'll be able to free the tractor by pushing aces under the wheels, so that she can bring the tractor back to her hometown.
