Il FraCodice. Il vero libro di How I met your mother

The list of rules feels both hilarious and surprisingly insightful about friendship. I wonder how many were based on real advice versus satire.

While the book is funny, some rules like loyalty and support seem to have deeper truths. Has anyone tried applying any of these in their own friendships?

The concept feels like a modern myth, but I’m curious whether the author drew from actual bro culture or wanted to parody it.
