If you trace the history of comedy across American television, you will find more than a few oversights and blunders in programming. Gigantic television networks are at the mercy of advertisers, and the people doing the advertising care, not about a show's content, but the numbers it produces. Got a impossibly huge audience in the coveted 18-49 demographic? You'll get the shiniest, most precious time-slot available. And, who cares if your show is filled with the same inane, recycled story-lines, with the same, neatly categorized characters you've seen a million times: the chauvinistic husband, the jolly-yet-stupid fat guy, the angry wife in high heels and on and on and painfully on. Who cares? You're pushing Pepsi and Pepto Bismol. You're moving mounds of Mounds and scads of Skittles. You're spoon-feeding America what they want to hear; you're doing the work for them, letting them kick their feet up and sit back, only moving when they laugh, on cue, with the fake audience that's also laughing. What a deep, Pavlovian mindfuck.
I've gone off the rails. What I'm trying to say here is: often times shows that take risks and go against banal convention are not rewarded. And it's a damn shame. There are many egregious examples: Arrested Development, Freaks and Geeks, Frank's Place, The Ben Stiller Show, and, case in point: The Dana Carvey Show.
