((OOC: The mun would like to point out that these articles are taken in their very barest form, without Barney's embellishments and examples, from The Bro Code tie-in book for HIMYM. The book has a LOT more stuff than this - I highly recommend chasing down a copy, especially the audiobook read by NPH. All the Paradisa Corollaries and extra rules, however, were written by me. ;D))
