Tom the cat is eyeing a row of prime number chicks (31, 37, 41, 43, 47, 53) with predatory glee, but then gets completely confused when he spots a 57 disguised as a chick. His mathematical predator instincts are short-circuiting because 57 = 3 × 19, making it decidedly NOT prime! Even cartoon cats apparently have better number theory intuition than some humans. Next time you're hunting primes, double-check your math or you might end up looking as bamboozled as Tom!
