In 1980, Hanna-Barbera got back into producing animated fare for primetime consumption. Naturally, it started with a new set of Flintstones cartoons produced specifically for primetime, this time on NBC, which was home to the Bedrock gang at the time.
The next attempt came as a late-season entry in 1982, but it's one that most of you probably haven't heard of. To tell you the truth, I never saw this show, because it was running during baseball season, and the Mets took precedence at my house. Still, Jokebook lasted about a month, didn't get much fanfare, and the material was such that it could probably pass as time filler today on [adult swim], provided of course the nimrods in charge even bother to find it in the vault.
