Characters
Bakabon's Papa (バカボンのパパ, Bakabon no Papa)
Bakabon's troublemaker father who eventually steals the show and becomes the central character. His catchphrase is saying "Kore de ii noda (これでいいのだ, It'll be all right)" to someone when trying to get them to go along with one of his stupid plans. A typical episode plot involves Papa either being too stupid to perform a simple task or coming up with some crazy idea to accomplish a simple task, usually asking for his son Bakabon's advice and causing tons of trouble. He was once very smart but became an idiot after an accident. He is known for always wearing his trademark hachimaki and haramaki. His favorite food is octopus. Papa has become an anime icon in Japan and was ranked number 9 in a 2002 TV Asahi Top 100 Anime Characters list.

In India this show was broadcast by Hungama TV.
The original series was heavily rerun on Animax during its first few years on air, as it was centred around classic anime at the time.

Notes
The official English name was Meet the Boneheads, but has since been favored for the more accurate The Genius Bakabon.
