So I was poking around this board, and I didn't find a link here. Anyway, there's this online webcomic named Skin Horse. This is not just one joke. It is a comic strip that is updated daily. I like it, and there is a pretty good chance you will enjoy it, too.
Let's have you start from the beginning: Skin Horse: Intro (http://www.webcomicsnation.com/shaenongarrity/skinhorse/series.php?view=archive&chapter=25034). Click the blue arrow pointing to the right to turn to the next page -- you will alternate between a Sunday sketch and a week's worth of four-panel strips.
My sources tell me this content is intended for people 16+ years of age.
