@JauntyArt at an old job, where upper management did no work, just toiled on powerpoints and awful business-speak rhetoric, one of them had the genuis idea of comparing us workers to cogs in a machine. An awful metaphor to belittle folks, and they didn't realize it. They displayed 3 gears in various sizes and numbers of teeth all interlocked with each other. I tried to explain that due to physics this wouldn't work and they didn't get it. Appropriately described working conditions there though.
