- Mr. Hellmann: Penno, can you play Mozart?
- Penno: No, I can't.
- Mr. Hellmann: Listen, if you'd play us Mozart, we would listen gladly. But this primitive bin-bin-bin... Stop it. Surely you don't think we like that? You definitely aren't *so* stupid!
- Mr. Markson: [commenting the discussion whether Penno should get the French exam "5" or "2"] "Three" to this dog enough is!
- Mr. Sirkel: A young person should know his limits. Otherwise it's the Canary islands at the age of eighteen, around the world at the age of twenty and then there is no place to go any more!
- [When the boys are telling him that there won't come an exam in math]
- Mr. Tusam: It won't come! It won't come! It won't come! But it will come!
- Mr. Tusam: History is like water: blow it away, squeeze it together - and you'll have a day and a half for mathematics.
- Mr. Tusam: This is, of course, a deliberate obstruction. And those, who organised it and those, who went along with it are all, more or less, blockheads!
