haw-haw

He looked like an animated drying-post, and the Dutch boy, in spite of his troubles, began to haw-haw wildly.

We ourselves laugh at a "haw-haw" intonation in English; why, then, should we forbid Americans to do so?

And Haw-Haw also tried some other whistling notes, different from the dog-call he had learned of Rick.

But, no matter how often this happened, he would always jump up and run out whenever Haw-Haw whistled.

Ruddy was growing wiser and Haw-Haw gradually stopped that trick, though he did not forget how to whistle.
