I sure do remember Hanna-Barbera's "Jokebook," it only ran three or four weeks. NBC was at an all-time low then, and was constantly churning their schedule. It was a sort of animated "Laugh-In" format made up of blackouts and short sketches, very untypical for an H-B product.
At least it was a lot better than "The Hanna-Barbera Happy Hour," which ran around the same time; a bizarre variety show hosted by two female Muppetlike puppets named Honey and Sis. The late Iwao Takamoto, who was H-B's chief character designer for many years, was also a puppeteer, and this may have been a "pet project" for him. It also featured a "rock band" of puppet vegetables called "Rudy Baga and the Vitamen!" I believe it had both live and animated "guests."
There's a kinescope clip of "Eye Guess" available at You Tube (along with a batch of clips of a couple guys playing their own video-game version, but this is the real thing...)
