Forget Robin Sparkles videos. The creators of How I Met Your Mother will soon be putting out something far more culturally significant: The Bro Code.

Those who followed Season 3 remember The Bro Code was something Barney Stimson (Neil Patrick Harris) violated when he ended up sleeping with Ted’s ex. Hoping to repair the relationship with his “bro”, Barney seeks Marshall’s legal help.

In the episode, we learned more about Stimson’s “list of Dos and Don’ts for all bros.” (You can see that clip from “The Goat” after the jump.) Articles in the book - which supposedly originated from a conversation between George Washington and Benjamin Franklin - include:

Article #1: Bros before Hos.
Article #34: Bros can not make eye contact during a ‘Devil’s Three-Way.’ (Two dudes.)
Article #89: The mom of a bro is always off-limits but the stepmom of a bro is fair game if she initiates it and/or is wearing at least one article of leopard print clothing.

A full-length version of the rules should be available for someone’s stocking this year. (The book is expected to be out in late November.)

Until then, the fourth season of HIMYM will debut on Monday, September 22.
