Warning: This comic is incredibly dirty yet no nudes. Digression is adviced http://greasymoose.com/comics/greasytales/02/greasytales02.html However this is my favorite image from it: I normally get my comics from Explosm.com however what comics have you found?
Scandinavia and the World. They like making fun of current events and history and stuff from around the world.
Definitely Beasts of Burden. I can't get the spoiler to work so here is an ending of one of the comics. Pretty dark which is why I like it.
Yea they burned in a fire and he's the only one who can see them like that. The rest of his group just see them as normal sheep.
Megatokyo- http://megatokyo.com/strip/1 Its an ongoing comic about 2 gamers stuck in Japan and the many misadventures they have.
