Joe Mathlete is on vacation

That is why nobody has been explaining Marmaduke lately. Yesterday was the 4th of July, and it's going to take at least another three or four days to properly celebrate the birth of America or whatever. Also, Ken Lay's suicide has yet to fully sink in, so wait until Monday or so to have Marmaduke explained to you (you can always try figuring the strip out on your own, but don't be too upset if it doesn't work. It is a difficult thing, understanding Marmaduke).
