?about the show SMALL WONDER from the 80s?

Situation comedies often do not have a stringent continuity, but are flexible from one episode to the next in order to maximize either the "situation" or the "comedy." So if in Episode 8 of "Ain't This Lucky?," if it is funny for Fred's 3rd wife to show up at his bowling night party, she will. But if in Episode 23 it is funny for Fred to have only been married twice when he's applying for life insurance; well, then, for that episode he will have only been married twice.
