Mothers hide all the children who lie
  Lockjaw's coming with a rusty nail
  He's gonna nail your mouth open wide
  Look out children
  Boys and girls who do falsify
  From the Black Forest with a hammerhead
  He's looking for you with a rusty eye

  In the Black Forest, lives an ogre named Lockjaw. Lockjaw doesn't like children
  who tell lies. Late at night he stalks the houses of the fibbers and the
  falsifiers, and before they can cry out from their beds, he nails their jaws
  open with a rusty nail, using his head for a hammer. You may escape him for a
  while and think you fooled him, but he'll get you in the end. He'll get ya!
  HE'LL GET YA!!

  Lockjaw's coming
  Hide your heads, all you lying children
  Mothers hide all your lying children
  Fathers hide all your lying children

  Look out mothers
  Telling lies to a gullible child
  Lockjaw's coming with a rusty nail
  He'gonna nail your mouth open wide
  Look out Fathers
  Teachers and leaders who do falsify
  From the Black Forest with a hammerhead
  He's looking for you with a rusty eye

  Many people wonder "Could such a terrible tail be true? Who would make up such
  a terrible tale?" It seems such a cruel punishment for such a tiny little lie.
  Well, I've got to confess. It's a fib. I made it up myself. It's pretty funny,
  don't you think? Ha, ha ha! Gag, gag, gag
