Venn diagrams Memes

Nothing triggers a mathematician's fight-or-flight response quite like a Venn diagram with "both" written in the overlap. It's like watching someone use the wrong formula but somehow get the right answer. The intersection should be labeled with the specific shared characteristics, not just "both" – that's the whole point of the diagram! Every time I see one of these abominations in a PowerPoint presentation, I physically age 5 years. The irony of using gears (which must precisely mesh together) to complain about imprecise logic is just *chef's kiss* perfect. Next up: pie charts where all the slices add up to 137%.
