Oh, the shark has pretty teeth, dear   And he shows them pearly white   Just a jack knife has old MacHeath, dear   And he keeps it out of sight      When the shark bites with his teeth, dear   Scarlet billows start to spread   Fancy gloves though wears MacHeath, dear   So there's never, never a trace of red      Oh, the shark has pretty teeth, dear   And now Macky's back in town
