惊急

惊 = 京 + 忄 : Somebody set off engine's alarm in the middle of the night and Joan of Arc arrives in a rush to scare away any intruder with a flail. She was in such a rush and so tired though that she forgot to put on her pants and arrives in front of the engine just wearing ridiculous underpants which feature a pattern of berets, mandarins and daisies.

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.
