And the shark he has his teeth and
There they are for all to see
And Macheath he has his knife but
No one knows where it may be.

Translation note: A "moritat" (a word meaning both "muderous deed" and "ballad") is a street song telling of murderous crimes. | Lotte Lenya, "Foreword", p. xii | Marc Blitzstein translation; largely used for Louis Armstrong's and Bobby Darin's pop renditions of "The Ballad of Mack the Knife"

Oh the shark has pretty teeth dear, And he shows them pearly white Just a jack-knife has Macheath dear And he keeps it out of sight.
