For so sworn good or evil an oath may not be broken and it shall pursue oathkeeper and oathbreaker to the world's end.
J. R. R. TolkienClap! Snap! the black crack! Grip, grab! Pinch, nab! And down down to Goblin-town You go, my lad! Clash, crash! Crush, smash! Hammer and tongs! Knocker and gongs! Pound, pound, far underground! Ho, ho! my lad! Swish, smack! Whip crack! Batter and beat! Yammer and bleat! Work, work! Nor dare to shirk, While Goblins quaff, and Goblins laugh, Round and round far underground Below, my lad!
