NOTE FROM JOE MATHLETE: Sorry, everybody... Imaginary Dental School has been ridiculously stressful lately (I lost my little tiny mirror on a stick thing, and they only give you one of those per semester), and I'm afraid I just don't have enough energy to explain the January 16 2007 edition of Marmaduke.

Fortunately, Marmaduke's owner-lady is doing a reasonable job of shedding some light on today's installment.
