Geba Geba is basically just a Yonkoma if it had animation between the panels, and for that it's quite good and still surprisingly funny. Each 'skit' only lasts for about 60 seconds and there's some gags in the transitions too. The animation is pretty decent, it's all simple but they didn't cheap out like they could have done with some things. There's no dialogue so you can watch this as is and get the point, but there are a few repeated music tracks that get a little repetitive after a bit. One thing I like is that there's alot of 'meta' humour, particular with the individual lines and shapes, it definitely feels a little ahead of its time and pretty outside the box for what could otherwise be a pretty boring OVA.
The only reason I saw this is because it got a very brief mention on a volume of the AnimeVision Video magazine, but unfortunately the only known sources have the last 5 or so minutes missing due to a damaged LaserDisc. I really did quite enjoy it compared to alot of the other generic OVAs from that period, very refreshing. I think that even though it's possibly the most obscure anime I've seen, most people would enjoy it.
One word of caution though, there is some nudity that's pretty random and weirdly placed in what is otherwise a kid's show, I suppose that's just the 80s for you though.
