Among the more popular premises for a sitcom is the fish out of water. Under this general rubric you will find many of the long-running shows of the last fifty years, often organized around the classic social situations: race, class, gender, and sexuality.

Race: The Jeffersons, which was an offshoot of one of the original fish-out-of-water scenes, the loosely veiled but still basically racial All in the Family, whose theme song (“guys like us we had it made… those were the days. … do you remember way back when, girls were girls and men were men… those were the days”) made it clear that Archie Bunker’s biggest problem was that he was a fish out of time — but of course for white folks to be out of time is always to be out of “race” as well. (If you have six minutes watch this amazing clip where Archie, late in the show’s run, takes on the KKK and calls himself “black”.) (Also in this category: Family Matters.)

Class: Two Broke Girls, The Fresh Prince of Bel Air (not Roseanne; I’m talking about sitcoms where the basic premise is that someone is out of joint);  Sexuality/Gender: Three’s Company comes to mind (but not Will & Grace). Something like Modern Family seems to be trying to wrap all of these up in a single package (which is interesting, because it has to produce wholeness out of that incongruous mix, but of course, that’s the point.)

But none of these categories quite capture the strangeness of the science fictional sitcom, in which the fish is an alien and the new swimming pool is the planet Earth. It’s so strange I think it’s easy to forget that through the 70s 80s and 90s the alien-on-Earth was a basic premise for television comedy. Mork & Mindy for the 70s, ALF for the 80s; and Third Rock from the Sun for the 90s. (There was also Small Wonder (amazing!! theme song), but that was about a robot.)

I have almost nothing to say about this but to that the other night as I fell asleep I was overcome with the marvel of this kind of sitcom. Aliens yes, but aliens and comedy just doesn’t seem plausible. I mean, what a crazy thing, no? It seems totally unimaginable that such a show would be on television today. And so I found myself wondering what kind of culture we are that used to allow these shows, and now doesn’t. It could all just be random noise, of course, but the critical, close readerly demand for total necessity leaves me wanting more.
