So ein Flegel

This is an earlier, much less successful version of the _Feuerzangenbowle_ , but the story is basically the same: The famous writer Hans Pfeiffer has problems in directing his latest play about a high-school class. He's told the reason is that he never attended a regular school, so he decides to swap roles with his younger brother Erich, who's a never-graduating, always kidding senior in a small-town high-school.
