a) III, i, (64-72) "To be or not to be- that is the question/ Whether 'tis nobler in the mind to suffer/ The slings and arrows of outrageous fortune,/ Or to take arms against a sea of troubles/ And, by opposing, end them".
-Whether Hamlet is contemplating suicide or contemplating if he should be the one to kill himself, this shows his level of crazy is at the point of wanting to do. His depression after his father's death is seems to increase even though time goes on.
b) III, ii, (109-101) "Excellent, I'faith, of the chameleon's dish. I/ Eat the air, promise crammed. You cannot feed/ capons so".
-This image of Hamlet describing himself eating at the air as a chameleon is not only freaky, but it shows a direct sky rocket of his insanity level.
