May be NSFW. Don't let the name fool you. They're actually pretty obscene and hilarious.

I actually was laughing in real life over a few. Heh. Enjoy. :)
Edit: As a word to the wise, the random comic button sucks, but it's worth going through them in order, because rarely do they disappoint.
Random button works as expected, you're experiencing the Birthday Paradox. :P
Also, while it's cool, they haven't updated in a long, long time. I'd say it's dead. :(
