[quote]Suddenly Grizzle saw a fine big duck swimming towards them, and she called out:

"Duck, duck, come to me,
Johnnie and Grizzle depend upon thee;
Take Johnnie and Grizzle on thy back,
Or else they'll be eaten—"

And the duck said,

"Quack! Quack!"

From "Johnnie and Grizzle", a version of "Hanzel and Gretel" where the witch-in-the-oven trick doesn't quite work out and a duck saves them. More at the source.
