Sun Wukong (儿) has a runny nose (mnemonic symbol for 允) and is constantly blowing his nose in the encampment ((e)n3). Yu the Great (yu) is very annoyed and tells him that it is not allowed (允) to blow one's nose in the encampment. Instead she hands him a fake nose (厶) with which he is to hide his real nose.

八
:
666 is the number of the Beast, so I'll represent 六 in other character's mnemonics as the Beast. Li Qingzhao is balancing a beret on an eight ball in the outhouse's bathroom, but suddenly the Beast appears and blasts it all.
