This monkey was not that unusual, in that he liked bananas, throwing feces, and to sit around, not observing (either visually, or aurally), nor uttering evil.
One day, the monkey was wandering around, minding his own business, when he happened upon a very complicated and involved combination bank robbery and puppy torturing in progress.
So second nature had the act of not seeing evil to the little monkey, and so pervasive was the evil around him, that he thought that he had gone completely blind. He stumbled around amazed, until he walked out of the bank, and got hit by a bus. (An evil bus.)
Happy Chinese New Year's!
