The series premiered in 1970.

The series is unique in one special way; it is the story of two British secret agents, Mortadelo and Filemón, who are blundering about with next to no plot lines! The short and absurd stories are pure slapstick, all served in a highspeed set of dynamic panels, and the events seem to drive even the many involved characters insane. Usually, the stories end the same way by the two agents delivering the tied up villain du jour to their boss in a great variety of ways.
