Here is a blurb.
"Who would have guessed that when you remove Garfield from the Garfield comic strips, the result is an even better comic about schizophrenia, bipolar disorder, and the empty desperation of modern life? Friends, meet Jon Arbuckle. Let’s laugh and learn with him on a journey deep into the tortured mind of an isolated young everyman as he fights a losing battle against loneliness in a quiet American suburb."
Here are a few examples of how much funnier, creepier, and honest to the brutality of life the comic strip becomes once you eliminate that pesky main character.
So check out Garfield Minus Garfield and I assure you that you'll rekindle a love for Jon Boy.
