You've probably seen Garfield Minus Garfield, a collection of Jim Davis Garfield strips in which Garfield himself has been removed, transforming the strip into a sinister portrait of Jon Arbuckle's descent into irretrievable madness.
But there's a good case to be made for Garfield without Garfield's thought-bubbles as the true standard-bearer for disorienting and unexpectedly great Garfield remixes. With this view, Jon Arbuckle is cast as a man who carries on detailed conversations with a cat, which is arguably weirder than the idea that he's merely wildly hallucinating.
