Quark (1977) was a really fun show, but maybe it came out at the wrong time. Buck Henry created it as a loving sci-fi spoof, and it's gentle oddball comedy that plays with Star Trek in a fun way. It only made it to eight episodes before NBC canned it but it still has a loyal fan base.
Richard Benjamin is Quark, commanding a United Galaxy Sanitation Patrol ship which of course gets into several scrapes that frequently echo Star Trek plots. Tricia and Cyb Barnstable are The Bettys (one is a clone of the other but neither will admit to being the clone), Richard Kelton is the Spock-like sentient plant Ficus, there's a male/female engineer called Gene/Jean, their boss Palindrome reports to a massive floating head, etc.
Not everyone is a fan of laff tracks, and some of the gags go nowhere, but it's entertaining and silly and captures the sometimes oddball '70s look of TV science fiction (I'm looking at you here The Fantastic Journey!) The Bettys wouldn't be out of place in Buck Rogers two years later.
