Following the popularity of Garfield Minus Garfield, it's only natural that the same thing is applied to other comics. Box Brown, the creator of the adorable Bellen (previously on Neatorama here), did this one: Dilbert Minus Dilbert.

1. Take comic strip
2. Remove main character
3. Profit!
His results with Dilbert are mediocre at best, at would only really parallel G-G if he removed everyone *but* Dilbert, or some other selected character.
Honestly, I think he sounds a bit jealous that this guy had a funny idea, and is making some cash from it.
In DMD you're left with a whole bunch of people in an office talking to themselves, and there's just on way suspension of belief is going to go that far.
Also without one strong character, it's just to meandering.
This is just another attempt to cash-in the success of that model, but Dilbert's setup doesn't allow for it to work as well. Even the Garfield that was translated to Chinese and back to English was only funny in one or two instances. Oh well, I suspect we'll see more attempts to steal GMG's spotlight before someone else tries -god forbid- thinking of something new.
