The brutal honesty of thermodynamics in one perfect cartoon! This meme brilliantly illustrates the second law of thermodynamics in action through a diesel engine. While some energy actually does useful work (the tiny mouse getting the good stuff), the majority gets wasted as heat, noise, and vibration (the big chunky guy hogging most of the energy). Engineers call these "parasitic losses" because they're basically energy vampires stealing power that could be moving your car forward. Even the most efficient diesel engines only convert about 40% of fuel energy into actual work - the rest just becomes your engine's mixtape of rumbles and heat.
