Rule 235 

The act of mentioning any potential fanfic's plot, whether sexual or not, will cause that fanfic to come into being in a publicly accessible location.

Robert: God, can you imagine a story where Jean-Luc Picard and Twilight Sparkle went on an adventure together?

Jean: Stop! Don't invoke Rule 235-- damn it, that story's on fimfiction.net now. "Discord's Prime Directive."

Robert: I'm so sorry.

Rule 708 

Rule 708 states to never go back to an ex-partner. They’re an ex for a reason, no apology or “life-changing” event will change that fact that you both hated each other for some time after you split. That hatred will always be there and you’ll both hold the breakup against each other even if you don’t realize it. The relationship the second time around isn’t love, it’s lust.

“My ex called me today talking about how she wanted to get back together, saying it was all a big mistake and she’s sorry”

“Don’t do it, remember Rule 708”
