相鼠 诗经

相鼠有皮，人而无仪。 人而无仪，不死何为？ 相鼠有齿，人而无止。 人而无止，不死何俟？ 相鼠有体，人而无礼。 人而无礼，胡不遄死？

Rat (literal translation)

The rat has fur, but man lacks propriety. If a man lacks propriety, why does he not die? The rat has teeth, but man lacks restraint. If a man lacks restraint, what is he waiting for before he dies? The rat has a body, but man lacks courtesy. If a man lacks courtesy, why does he not die quickly?
