A wolf sees a lamb drinking from a stream and decides it wants the lamb for its supper. The wolf tries to come up with excuses to seize the lamb, first accusing it of muddying the water, but the lamb explains that is not possible as the water flows downhill. The wolf then accuses the lamb of insulting it the previous year, but the lamb points out that it is only six months old. Despite the lamb's reasonable responses, the wolf attacks it anyway, showing that tyrants will use any excuse to justify their actions. The moral is that any excuse will serve a tyrant.
