Yes, that’s based on an actual cartoon. The “write your own joke” gag is also from here and here.
Speaking of Mr. “Conservative and with a duck“, why is it that so many conservative humorists’ impressions of liberalism are completely stuck in the mid-90’s (at best)? Sure, they mention more recent figures like Howard Dean, but conservative hacks like Tinsley are always dating themselves with endless references to Ted Kennedy’s drinking, Bill Clinton’s infidelity, and Barbara Streisand. It’s not like lefties are still telling jokes about Ollie North, Jimmy Swaggart, and Ross Perot. As Jack Chick says, HAW HAW HAW.
My guess is that for conservatives like Tinsley, whose worldview revolves around the idea that mass media is intrinsically immoral and/or politically-biased, their shunning of the society they’re commenting on makes their decent into cultural illiteracy inevitable. In a fair world, they’d be treated like the disgruntled, out-of-touch loons that they are, but in the interest of “balance”, their work is promoted to the same level as people who know what the hell they’re talking about. I can’t help but think that if this sort of thing were happening in any other field, it would launch a thousand self-righteous lectures from the right about “reverse affirmative action” or something equally silly.
