Finally, a mathematical formula more elusive than the Riemann hypothesis – the probability of romantic interest. What we have here is Bayes' theorem masquerading as relationship advice. Turns out, calculating quantum field equations is still easier than figuring out if your crush likes you back. The denominator should include a term for "number of times you've rehearsed this conversation in the shower" divided by "actual courage to speak when the moment arrives." Trust me, I've been teaching probability for 30 years, and this equation still returns "undefined" for most grad students.
