These shows are the replacement for Fraiser as comedies that don't insult the intelligence of the viewer. They play up to it. I don't know which "blink and you'll miss it" joke was better in the last episode:
The one about "We're absolutely not making fun of Andy Griffith" (the joke being that Ron Howard does the voiceover) or the one about having your picture made with Saddam Hussein is not always a career killer (followed by a two-second flash of a photo of Rumsfeld shaking hands with Hussein in 1982).
