I ran into Porkcow on DeviantArt a while ago and I figured I'd link to him 'cause he's awesome.
He does a lot of super detailed but grotesque fan art, which is pretty great. He's also prone to doing random computer doodles, but even those usually come out with massive amounts of style which is just so wrong.
A random assortment of stuff:
-WeeGee Mask
-Creepy Mighty Mouse May contain mouse nipples.
-SpongeBob...err, I mean, The Gary Show
-Mayor McCheese sketches Part of a series of McDonald's mascots. Be sure to red the description.
-Simpsons
Yeah, I think that's a good enough selection. Enjoy!
