Hey, weirder things have been pitched in the past.

I think The Office is maybe a good example of what we're talking about. I'm not sure if that show intended things to be self contained from ep to ep, but even when there are huge plot points (someone leaves, someone is promoted, someone has a baby) it still feels like each show is basically the same. They may change position or something, but generally the show doesn't change from episode to episode.
