Due to the /b/ section being overrun with users from sites such as Gaia Online and MySpace, these rules were accepted, and more people took part in the illusion that 4chan is a SUPAR SECRAT CLOBHAUS. Despite the fact that these two rules state that you shouldn't talk about /b/, some people will cite "RULES 1 AND 2!!" every time 4chan (or even a meme) is mentioned outside of the site.
Thankfully, this vermin of stupidity remains contained in /b/, so people who cite rules 1 and 2 in other boards are bound to get flamed and hopefully banned.
Idiot: RULES 1 AND 2 BITCH
