See No Evil, Hear No Evil, Speak No Evil

Mizaru, covering his eyes, sees no evil. Kikazaru, covering his ears, hears no evil. And Iwazaru, covering his mouth,  speaks no evil. The three together are the wise monkeys, an ancient reminder of ethics and code of conduct, here depicted brilliantly by builder J.B.F. While the notion of being a wise monkey seems appealing, I would like to hesitantly propose the 4th monkey, "have no fun".
