凶猛

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.

猛 = 孟 + 犭 : Mencius' (孟) dachshund (犭) did a dump inside of the engine ((e)ng3) and Mencius is furious (猛). He ferociously yells at his dachshund and is in turn yelled at by Mahatma Gandhi (m) who oversees engine.
