My favorite webcomic is Buttersafe
http://www.buttersafe.com/Its pretty neat, its got two artists who make different styled single paged gags. Its similar to like XKCD in the tone of the humor except its not nerdy jokes and its funny (heh get it I just said xkcd isn't funny (just kidding xkcd can be funny sometimes but its mostly hit and miss))
