As discussed before, I currently have an arrangement with Viz where I can send them ideas for strips in rough form for consideration for publication. Here are a few that they didn't want.
I always felt that the title for this one was a bit lame but the strip as a whole worked. Obviously, Viz didn't agree with my second assumption.
I like to think that this one got rejected because of the sheer quantity of dentist strips Viz already had in the slush pile to print.
