六 = 亠 + 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.

体 = 亻 + 本 : Rosa Luxemburg envies Mother Teresa's hot body. She asks her how she can be such a hottie even when lifting is not possible, like in the space station's zero gravity, and Mother Teresa answers that it's because of the roots she's eating.
