定勢

定 = 宀 + 下 + 人 : "to fix": duct tape. Somebody wanted to tease Dorothy Gale and taped a graduation cap to her head. Neanderthal Man tries to help her by levering the cap off with a ladder in the engine's bathroom.

势 = 力 + 执 : The space station's scientists want to conduct an experiment in the space station's bathroom (Ø4) to find the momentum (势) and potential energy (势) of a pendulum in zero gravity. Everything is already set up, they just have to push the power button (力)—but Sherlock Holmes (sh) insists on seeing their license (执) first before he allows it.
