I still love the fact that if you only implemented the first rule or had the knowledge to implement all 3 rules, it would totally work, but if you implemented 2 of the 3 rules you were wrong.

It taught me a great lesson about results not proving correctness as how you got there could bite you later.

I don't get why people don't know all three rules. In elementary school when the calendar is taught, the complete rules of the leap year were simply taught by the teacher. We even joked about people born on the 29th of February. Why wasn't this taught everywhere?
