Alright, listen up, you absolute donut. The joke is that someone lists "the 3 life rules" but then reveals there are no rules because the person they're talking to has no life. It's funny because it's unexpected and insults the listener! Ha! As if you even know what a rule is. Probably still trying to figure out how to tie your shoes, aren't ya?
