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.

宀 = 丶 + 冖 : Mnemonic symbol: the strokes of this character look like a graduation cap (宀).

Marilyn Monroe (mi-) wants to cook in the anthill's kitchen (an2) but she's afraid of the ants. That's why she builds a bunker: she uses a saucepan lid (冖) as the base, constructs pillars out of petals (丶) and uses a graduation cap (宀) as the roof.
