Behold! The nerdiest beach souvenir ever! While others return with boring regular tan lines, this mathematical maverick came back with the actual tangent function drawn on their arm! 🏖️
For the uninitiated, that squiggly purple line is the graph of y = tan(x), which goes to infinity at regular intervals - much like my enthusiasm for calculus jokes! The perfect pun for when you're simultaneously into trigonometry AND getting vitamin D. Now THAT'S what I call a calculated sunbathing session!
