I still love the hell out of "Sports Night," and it's equally interesting as a laff-trak study. ABC didn't know what to do yet with a single-cam sitcom and insisted on a laff-trak being flagrantly tacked on. Sorkin et al. naturally hated that, and gradually lowered its frequency and even volume, until by the end of the first season it's practically nonexistent. And I think it's gone entirely for the second season (though it's been several years since I revisited). The pacing and editing in the early eps are definitely done around the laffs piped in, and it feels so awkward.
I'm also proud to say that I'm one of apparently 10 people in the U.S. who watched the shit out of and evangelized for Tim Reid's "Frank's Place" for the all of 30 seconds it aired (felt like). Another single-cam sitcom but with no laff-trak slapped on it; wall-to-wall sharp, funny, unpredictable (the homeless man ep killed me), and talked up to the audience.
I remember watching the News Radio pilot purely out of Dave Foley interest (Kids in the Hall were HUGE to me at the time), and by the end realizing I'd actually seen an American sitcom that reminded me in pace and quality of nothing less than Fawlty Towers (the gold standard, all-time champ, no arguments to be brooked, though this thread seems to be sticking to U.S. fare) (ETA: not to mention newish to modern, duh-doy).
