己亥

This character looks like a butcher's hook. In the space station, Joan of Arc wants to conduct an experiment about a sixth order chaotic pendulum. First she hooks a butcher's hook to a sickle, then sticks the sickle's end into a flute, and finally hooks the handle of a shovel into the last hole of the flute. She then swings the chaotic pendulum to observe its behaviour.

亥 = 亠 + 厶 + 人 : Mnemonic symbol: a boar.

亥 = 亠 + 厶 + 人 : Hamlet is terribly afraid by a beret-wearing boar in the airplane's bathroom, but fortunately Neanderthal man is there to protect him and to fight of the boar with a huge fake nose.
