rule34.paheal.net 

A cartoon/hentai website that is a lot like rule34.xxx but it has even more stuff. However, it’s tagging system can get pretty confusing at times and it’s search system is not as good. Still worth checking out though

Rule 38 by Elite CAT October 31, 2008

rule34 

There is porn of it, no exceptions. It is an internet based "rule" derived from a set of generalizations about things you will find on the internet, this one basically referring to how no movie, show, books, or especially children's cartoon is safe from having porn drawn of its characters. It is usually accompanied by people who claim viewing it has "raped their childhoods."
If there is no porn of it, which is of course impossible, it invokes rule35: if there is no porn of it, porn will be made.

Guy 1: There is no porn of The Lion King. It's a child's cartoon!

Guy 2: Have some rule34. *shows porn*

Guy 1: Nooo, my childhood! *cry*

Rule 38 

Rule 38 is a prison offence in which someone is masturbating in public.

He got locked up because he kept doing a rule 38 in front of the female prison guard.
