If you haven't visited the oddness that is garfieldminusgarfield.net, I encourage you to take a peek.  The creator simply takes old Garfield comics and removes Garfield himself,  "in order to reveal the existential angst of a certain Mr. Jon Arbuckle.  It is a journey deep into the mind of an isolated young everyman as he fights a losing battle against loneliness and depression in a quiet American suburb."

It has a quiet sort of weirdness that appeals, certainly more (for me at least) than the original comics. 

It's worth noting that Ballantine Books is publishing a book with the original strips and these doctored comics set on the same page, so that readers can see both and decide for themselves which they prefer.  Garfield creator Jim Davis even likes 'em, saying "“I think it’s an inspired thing to do,” Davis said. “I want to thank Dan for enabling me to see another side of Garfield. "

Even if you don't like Garfield -- perhaps especially if you don't like Garfield -- check this out when you've got a moment.
