The perfect intersection of biology and statistical probability! Nothing triggers a biologist faster than someone insisting whales are fish. The meme brilliantly shows how this misconception follows the bell curve of intelligence - both the extremely dull and surprisingly bright ends somehow reach the same wrong conclusion, while the average person correctly identifies whales as mammals.
It's the horseshoe theory of taxonomic ignorance - where the extremes meet in magnificent wrongness. The middle guy crying tears of frustration represents every biology teacher who's had to explain for the 500th time that having fins and living in water doesn't make something a fish. Convergent evolution is cool, but classification isn't based on "vibes."
