Hear no evil

The three wise monkeys sometimes called the three mystic apes, are a pictorial maxim. Together they embody the proverbial principle “see no evil, hear no evil, speak no evil”. The three monkeys are Mizaru, covering his eyes, who sees no evil; Kikazaru, covering his ears, who hears no evil; and Iwazaru, covering his mouth, who speaks no evil.

This one hears no evil.
