Rule 34 of the Internet
XKCD is a comic that I really like. Just read it, it's great. Anyway, this one in particular stands out to me as oh so true.
(Note: yes, wetriffs.com does exist now :)
In the last 12 hours, it's been proved to me twice.
I found this about 10 minutes ago (actual url hidden to protect the guilty - and I know this guilty person personally):
No, it's not porn. But I can't help but fit it into a superset of rule 34, which is simply that if you can imagineit, it can be found on the internet.
And then there's this next link. Please, don't follow it if you're easily offended. Or at work. Or if your speakers are turned up too loud. Or if there's kids nearby. Or if there's anyone around at all. Hell, just don't look. Don't look here. omg.
