己丑

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.

丑 = 二 + 刀 : Charlie Chaplin (ch) finds a very ugly (丑) ox (丑) in the outhouse (ou3) and decides to destroy it with a cleaver (刀) because it is so ugly. He'll soon notice that the ox has been hooked up to a charged capacitor (二) so that anyone trying to damage it will be shocked.
