A single-panel stick-figure comic. A stick figure stands with one leg raised and holds a small hammer near it, saying, "Listen up, leg. I've been sending you rich, oxygenated blood for years, while you send me worthless used-up blood with no oxygen. Time to teach you a lesson about not ripping me off!" Caption below says "Tariffs". Hidden text: "You legs may have a comparative advantage at running, but we arms have a competitive advantage at swinging hammers, so unless you accept that we're the dominant limbs and stop hogging the oxygen, that running advantage won't be around for long."
