Oglaf is a web comic that you should avoid at all costs.
First off, it is almost guaranteed not safe for work. Half of the weekly episodes, which drop every Sunday, feature nudity, blatant sex of absolutely all persuasions, drugs, wayward dieties, and pretty much everything that would get your face slapped if you weren't laughing so hard. My favorite episodes are Vorpal Blade and Hello Twiggy. I cackle like an idiot whenever I read these, and they're some of the tamer episodes.
If you need a good laugh or want to feel insulted, or even want to give the Wish Dolly a try, stop over and start reading. You won't get anything else done for hours.
