[4] [5] Oktaaf Keunink centers around an old pipe smoking office clerk[6] who is dominated by his bossy wife Beva.

His home address was also specified in the series, namely Kladderpoelstraat 9 in the fictitious village Zwaaigem (a pun on Aaigem or Baaigem).

[7] A running gag is Oktaaf's desperate attempt to play cards with his friends in his local bar, even though his wife repeatedly tries to keep him home.

[8][9] He also has a rivalry with his neighbour, Balk, who looks a lot like Slager Janssenss from Sleen's other series Doris Dobbel (both characters were caricatures of Jan De Spot, a journalist who was one of Sleen's personal friends).

[11] In 1971 Herman De Coninck and Piet Piryns interviewed Marc Sleen for the magazine Humo.
