尿急

尿 = 尸 + 水 : Nefertiti (ni) is drinking from a water fountain (水) in the aorta's bathroom (ao4), but she doesn't notice that at the same time a ghost (尸) is peeing (尿) into the water fountain.

急 = 刍 + 心 : Joan of Arc just arrived at the space station and although she has to go to the bathroom very urgently, she first has to clear the way of a big fluffy heart using a lawn mower.
