An understanding simple and unschool'd:
Note the inherent irony here, that Hamlet has just left the prestigious university of Wittenberg. He is not simple at all. Can it be that Claudius is intentionally baiting his nephew, and at the same time, asserting his political power over him? Perhaps he feels that, if he gently ridicules Hamlet, he will force him to obey.
