Based on Fujio Akatsuka's subversive family comedy, the series follows naive 10-year-old Bakabon and his folks: Papa, the patriarch and idiot supreme, Mama, Bakabon's darling mother and voice of reason, and Hajime, the newly-born baby boy who, due to being in the womb for an extended period, gained super-intelligence and an extensive bevy of worldly knowledge. Much of the comedy revolves around the idiotic natures of Bakabon and his Papa, and the people who have to put up with it.
