The moment
Chief Bromden's suffocation/mercy killing of his lobotomized friend and his escape from the mental institution by throwing an immovable sink through a window.

Why we get choked
McMurphy (Jack Nicolson) is the lone voice of the patients in this sterile environment of rigid authority. Where drugs, treatment and therapy have failed, McMurphy's death at the hands of his friend suggests the notion that perhaps the only path to true freedom for the souls in the institution is transference to the afterlife.

Maybe it's that moment when Wind in his Hair asks Dances with Wolves if he can see that "he is his friend" and tells him that he "will always be [his] friend" that we missed.

Do you agree that this moment is one of the best?
