If an object can be conjectured, there is porn made of it. If not, then porn will be made of it as soon as someone hears what you are looking for. (see rule 34-B)
Known exceptions are:
Rule 34 itself. You cannot rule 34, rule 34.
Also, abstract ideas may not be rule 34'd, it must be a concrete object or be representable as one.
Anything and Everything on the internet has been made into a porn. You just have to look hard enough. Only exceptions are as follows:
>Chuck Norris (duh)
>Rule 34 (you can't rule 34 rule 34)
>Abstract objects (you can't rule 34 happiness)
guy - Oh. My. God.
girl - what?
guy - I just saw a rule 34 for my mother.
guy 2 - do you like it? made it myself.
girl - I'm leaving now.
