Masochism Memes

The infamous Griffiths electrodynamics textbook showing its true colors with "Problem 1.23 (For masochists only.)" highlighted in yellow. Nothing says "I respect your weekend plans" like a physics textbook openly admitting it's about to ruin your life with vector calculus proofs. The author could've just written "difficult problem" but chose violence instead. This is the academic equivalent of a chef sprinkling ghost peppers on your food while maintaining eye contact.
