吉凶

吉 = 口 + 士 : Mnemonic symbol: "Giga" apparently stems from a Greek word for "giant", so I'll represent 吉 by a giant.

The giant (吉) just entered the space station's kitchen (Ø2) and is very hungry. In each hand he holds Joan of Arc (ji) and the bachelor (士) captive and robs them for their mandarins (口) which he longs for.

凶 = 乂 + 凵 : Mnemonic symbol: a vicious (凶) demon mask. Xu Xian (xu) tried out an electric demon mask (凶) in front of the engine ((e)ng1), but now he can't take it off anymore. He already tried to pull the cable out of the receptacle (凵), but it didn't work. Maybe he has more luck using pliers (乂) to pull at the mask.
