It's a terrible thing to have a web-linked computer sitting in front of me in class all day. Then again, how else would I have to chance to expore the amazing artwork of Bent Objects? I think the creepy fry-spider is my favorite. Office supplies in the wild is pretty good, too.
Also a great time, check out Steve, Don't Eat It!, a subset of The Sneeze. The rest of the site is a bit juvenile and profanity-laden, but there's some good bits, too.
