"AKATSUKA Fujio's iconic gag manga, Tensai Bakabon, is a best-seller whose name is recognized by almost everyone in Japan. Saying "Yeah, this is fine!" the Bakabon family cause everyone around them to howl with laughter. Fishing in puddles, playing with an invisible dog, taking a bath with clothes on... Today, too, those in the Bakabon family are being tricked into doing silly things."

Tensai Bakabon (Or, "The Genius Bakabon" ) is a gag manga starring ironically the titular character's father, only known as "Bakabon's Papa". The manga generally centers around episodic stories of Papa causing trouble around town due to his own and his son's complete and utter incompetence. This usually attracts the attention of the local trigger-happy policeman "Honkan", as well as causing issues for Bakabon's mother (Also just known as "Bakabon's Mama" ) and his younger, but extremely intelligent brother, Hajime. While the series is quite old, many of the jokes and stories are timeless in execution, and hold up well today, which is largely why it's considered a classic series in Japan.
