九 = 丿 + 一 + 乚 : Joan of Arc is on cloud nine in the outhouse. With a shovel, she dug up a banana: when she peeled it she found a flute inside, with which she instantly fell in love.

运 = 云 + 辶 : Yu the Great (yu) is practicing step dancing in the encampment's bathroom ((e)n4). She is wearing gladiator sandals (辶) and is moving (运) so fast that she's evaporating the floor. There are even clouds (云) of smoke coming from her gladiator sandals and the evaporated floor.
