I enjoy White Ninja. In fact, I've thought of posting them here before when new ones come out, like we do with Perry Bible and PA, but I never got around to it.
One bored day at work I just read every single one. They're not all winners (but I've read no comic that is 100% consistent), but a large percentage of them are hilarious.
