They believe that the loss of his father and his overwhelming love for Ophelia have driven him mad. His rants and ravings towards and around these characters are used as evidence against his sanity. However, after examining Hamlet's lines, especially those in the dialogue between Hamlet and the others, one will find that Hamlet is playing with the heads of other characters, especially the ones he doesn't like. Hamlet mocks other characters by being sarcastic or mocking them. When viewed from the perspective of the opposing character, this can be seen as incoherent and irrational speech. However, these exchanges and Hamlet's seemingly illogical responses are simply mind games on Hamlet's part. An example of this can be found in Act 3, Scene 2 which begins at line 100, when Polonius boasts about his acting and Hamlet mocks him. Using puns, Hamlet mocks Polonius by saying, “It was a brute part of him to kill so capital a calf there” (105). These exchanges continue throughout the play and often leave Polonius confused and certain of Hamlet's madness while Hamlet is secretly laughing at Polonius.’
