As it turns out, Garfield is brilliant

[Sacred Jellybean]

I wonder how much Jim Davis still has to do with the comic. I wouldn't be surprised if he left it to ghostwriters years ago... it's such a simple cut-and-paste, canned-joke comic (hell, most of it is Garfield making wisecracks to Jon on a table), coupled with the fact that Davis sees it as more of a business than an art, that I wouldn't be surprised if he just plays golf all day and gets a check from Universal every week.
