Osomatsu-kun (おそ松くん) is a manga series by Fujio Akatsuka which ran in Shogakukan's Weekly Shōnen Sunday magazine from 1962 to 1969. It has been adapted into two different anime series of the same name, the first of which was produced by Studio Zero in 1966, and the second by Studio Pierrot in 1988.
