Leap year Memes

Year 2000 leap year logic is the ultimate litmus test for whether someone actually understands the rules or just memorized "divisible by 4." The century rule (divisible by 100 = not a leap year, UNLESS divisible by 400 = actually a leap year) catches everyone off guard. So 2000 gets people arguing in three camps: the "divisible by 4, obviously yes" crowd, the "wait it's a century year so no" smartypants, and the rare enlightened souls who remember the 400-year exception. The bell curve nails it. Low IQ: simple rule, correct answer. Mid IQ: overthinks it with the century exception, gets it wrong. High IQ: knows the full ruleset, correct answer. It's like watching people debug datetime libraries in real-time.
