* AnimationAgeGhetto: What got the show canceled in its initial run. MoralGuardians didn't like that a cartoon was dealing with family unfriendly subjects, even if it was explicitly not for families. It didn't help that the show was originally designed for, and for the most part aired in, the new 7:30 family slot.
* EarWorm: [[https://www.youtube.com/watch?v=-lKeifVz3b8 The theme song]].
* SeinfeldIsUnfunny: It can be difficult to appreciate how risky it was just to do an animated series exclusively for adults in the 1970s after their resurgence in the 90s.
* ValuesResonance: Despite dating itself by taking on contemporary issues, much of the edgier content has held up (mostly because several of the issues, for better or worse, never really went away so much as took on new forms). Some of the show's handling of feminism (especially the episode where Irma gets a job at a law firm and the younger, prettier secretary is treated better than the older, plainer Irma), and population control ("Expectant Papa") are still relevant in the 21st century. It helps that the show never stooped to the kind of [[BottomOfTheBarrelJoke scatological or racist humor]] that [[AllAdultAnimationIsSouthPark many animated shows for adults rely too heavily on]].
* WhatDoYouMeanItsNotForKids: This show is best described as ''Series/AllInTheFamily'': The Animated Series. Too bad most people at the time saw cartoons as being frivolous kiddie fare, not helped by most of [[Creator/HannaBarbera the studio's]] other content being exactly this. Creator/CartoonNetwork even aired it in prime time during its inagural run (this being before the creation of Creator/AdultSwim). It wouldn't be until ''WesternAnimation/TheSimpsons'' came along in the late 1980s for people to see the light.
