Blondie is downright hysterical compared to Marmaduke.
As a fair and balanced dog, you must find that Marmaduke is
just offensive in its failure to deliver.
As a matter of fact, this would be a cutting remark for the terminally unfunny:
"Do you write for Marmaduke?"
The lower wits would be flattered, while the dogs in the know would nod their heads knowing that they were just given a little doggie present.
