Marmaduke has prominently displayed numerous diplomas from various dog-related educational institutions on the exterior of his doghouse; their gratuitously conspicuous placement, along with his smug facial expression, indicates that Marmaduke is putting on airs in order to impress his neighbors.

In the real world, the scenario depicted in today's Marmaduke would be highly implausible.

Marmaduke is being taken for a walk/sprint by his owner-man, who chastises the beast for his unwillingness to carry his own enormous goddamned bone.

Marmaduke ate his owner-lady's cell phone. It is unclear if his motivation was hunger or spite. Also, his owner-lady is named Dottie.

Marmaduke's owner-man has not yet come to terms with the fact that he is his pet Great Dane's bitch.
