The ultimate math flex! On the left, you've got the Pythagorean theorem tattoo - clean, elegant, fits on a single line. Then there's the competition with a full arm dedicated to Taylor series expansions, Euler's formula, and basically an entire calculus textbook. Who needs muscles when you can flex with mathematical equations? The perfect example of "tell me you're a math major without telling me you're a math major." That exponential function tattoo is definitely an irrational decision!
