I Don't Get It

Seriously, can ANYONE explain what the fuck Brad Anderson is talking about?
Ok, the dog's wearing a shirt... how do we make the jump to the Internet?
Marmaduke reminds me of Bil Keane's half-witted puns at The Family Circus but worse. At least Keane's got a bunch of grandchildren (and probably great-grandchildren) he can draw on for "inspiration" or whatever dementia drives the man on. No Marmaduke is like Ziggy, only less funny.

Marmaduke was created in 1954. The average lifespan of a real Great Dane is 7-10 years. The average lifespan for a 1-panel comic chronicling the mischief of a Great Dane is probably about 3 years.
