惊错

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.

错 = 昔 + 钅 : Kitty Cat just finished polishing her golden harpoon in the observatory's bathroom, but afterwards she made the terrible mistake of dropping her milkshake on it. Now she'll have to polish it all over again.
