The comics blogosphere is full of the snark. But nobody does it quite like Tim at The Hurting, whose snarkarama "Comic Remixes" will either make you laugh until the beverage of choice comes shooting out of your nose. Or they'll get Tim sued. Not quite sure which.
Check out his "remix" of Avengers #500 here, of Astonishing X-Men #4 here and his "Identity Crisis #3" remix here. (Hint: they're funnier if you read the actual comix, but not always.)
