A probability density function with the most whimsical heavy tail in the field. The cat IS the distribution: a sharp rise on the left, a vertical axis through the mean, and a tail that doesn't decay so much as swoop up into a fat curl over the cat's head. Pure visual humour — no, real PDFs are not allowed to do this, that's the joke. For data scientists, statisticians, quants, actuaries, risk managers, ML researchers, and anyone who has ever had to explain that variance can be infinite. Pairs nicely with regressions you don't trust and bootstraps that just won't converge. Sister design to the loafing-cat heavy-tailed shirt; same joke, more whimsy. Minimal line art in white on dark or black on light. Vector design — sharp at every print size.
