This is a lost artifact that shouldn't exist, resurrected by the person who made it in 1969 because the originals were gone. Renzo Kinoshita didn't remake what he'd done; he built something new from the same broken pieces, gags firing so fast you can't catch your breath between laughs. It hits like a time machine that runs on pure comedy instinct, no story to slow it down, just a old man and whatever he decides is funny today.
GebaGeba Ojiisan, the star of Renzo Kinoshita's animated segments on the 1969 variety program Koizumi x Maebue Geba Geba 90-minutes!, returns in this single-episode comedy OVA. Many tapes of the original broadcast were destroyed back then, and those animated bits were lost with them. To bring them back, Kinoshita produced an entirely fresh set of short gags built around the same character, reviving a missing piece of the old program.
