守勢

守 = 宀 + 寸 : Sherlock Holmes just graduated from police school and stands guard in the outhouse. Still wearing his graduation cap and carrying a huge shield, he's protecting the outhouse's art. The visitors are a bit afraid of him, so he thumbs up to show them that there's no danger from him.

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.
