King David was a righteous king, A shepherd loved by God, And Joab did the ugly work Without a single nod. A principal can stroll the halls, Grandfatherly and kind. His number two’s the children’s bane, Reviled in student mind. The highest of the high can shine, All warmth and lenity, Their trusted second is the sting. Cursed in synecdoche. Every Adama needs a Tigh, All discipline and screeds, Since troops can sooner love a chief Untainted by cruel deeds.
