Marmaduke: He got some sort of stimulus package.

This cartoon is hilarious because it mentions the phrase "stimulus package," but the usage of the phrase within the context of the cartoon is entirely inexplicable. Are we to take it to mean that Marmaduke has received money from the federal government? If so, for what? And why is what I presume to be a check arriving in a large box? Or is it just a regular package that Phil is humorously labeling a "stimulus package"? Or is it euphemism for some sort of bizarre animal sex toy?

Really, the moral of this cartoon is that Marmaduke should never go topical, as doing so inevitably ends in disaster.
